Its main goal is detecting terrestrial planets in the habitable zone of  solar type stars. With its huge FOV\, most of the PLATO targets are bright stars that will be monitored with high cadence (25 s) for at least 2-3 years during the long duration observing program\, while contemporary a number of very bright stars in the sample will be observed with 2.5 s cadence. The collected data\, photometry from space and high resolution spectroscopy from the ground\, will provide accurate planetary structures as well as  architectures and evolutionary stage – via asteroseismic analysis – of a large number of planetary systems. PLATO is planned for a launch in Dec 2026. \nMore information on PLATO are on the ESA website and in PLATO Mission Consortium website. \nWith  PLATO Mission due for launch soon  this would seem a good time to review the present state of knowledge of exoplanet systems and the objectives of the mission. PLATO is optimized for the detection and characterization of small planets in the habitable zones of Sun-like stars. By combining two cutting-edge approaches: planetary transits and the study of the internal structure of stars using stellar seismology\, supported by a dedicated ground-based observation programme.In combination with a dedicated ground based observation programme\, PLATO will provide accurate planetary parameters (including age) for a large sample of exoplanets which could be used to answer many scientific questions eg if there are favoured evolutionary paths for exoplanets by comparison with theoretical population models PLATO will provide accurate and complete planetary parameters (including age) for a large sample of exoplanets\, allowing to address a variety of scientific questions: planet occurrences\, trends in composition\, dynamical evolution\, favoured evolutionary paths\, etc. \nThe aim of this conference is to review the current state of the art in the field and to examine the range of scientific questions PLATO data could prove useful. Themed sessions will examine planetary systems at all stages of their evolution as well as give an overview of the PLATO mission\, its  future data\, and how to become involved. \n  \nSESSION THEMES \n1 – PLATO mission – where are we?2 – PLATO Science – From Stars to Planets3 – System architectures from observations4 – Advances in planet formation5 – Exoplanets Evolution6 – Relevant Stellar Science \n\n  \nMore info URL:https://www.oact.inaf.it/event/esp2024-plato-planetary-systems-formation-to-observed-architectures/ LOCATION:Department of Physics and Astronomy “Ettore Majorana” (DFA) of the Catania University\, Via Santa Sofia 64\, Catania\, 95123\, Italia CATEGORIES:Eventi & Seminari ATTACH;FMTTYPE=image/jpeg:https://www.oact.inaf.it/wp-content/uploads/2024/04/PLATOESP2024_Poster-2.jpg END:VEVENT BEGIN:VEVENT DTSTART;TZID=UTC:20240514T210000 DTEND;TZID=UTC:20240514T223000 DTSTAMP:20260404T193714 CREATED:20240512T094414Z LAST-MODIFIED:20240512T094417Z UID:16268-1715720400-1715725800@www.oact.inaf.it SUMMARY:Pint of Science 2024: La conquista dello spazio DESCRIPTION:Nell’ambito dell’iniziativa “Pint of Science“\, che si propone di promuovere incontri con ricercatori in un ambiente accogliente e informale\, vi segnaliamo la seguente iniziativa\, che si svolgerà presso il Joyce Irish Pub\, Via Montesano 46 – Catania. \n \n \n \n \n \n \nTitolo: La conquista dello spazio \nSommario: Partendo dallo storico viaggio di Gagarin\, si parlerà di come il genere umano ha conquistato lo spazio che ci circonda\, delle prospettive future a breve e lungo termine e\, per i pochi a quel punto ancora ragionevolmente sobri\, delle ricadute sulla vita di tutti i giorni delle tecnologie spaziali. \nImmagine Credits: ESA liberamente modificata da Daniela Sicilia \nRelatore: Giuseppe Cutispoto (Primo Ricercatore – INAF Osservatorio Astrofisico di Catania) \nLaurea in Fisica e dottorato in Astrofisica a Catania.

Potrete infatti giocare a PIXEL – Picture (of) the Universe\, il gioco da tavolo sulla risoluzione in astrofisica o a Cosmo Hunters\, gioco di carte sull’osservazione degli oggetti celesti\, senza dimenticare il Code Hunting Game\, una caccia al tesoro virtuale nel mondo dell’astronomia che vi permetterà di entrare nel mondo del coding. Per gli appassionati di giochi a quiz c’è poi Chi vuol essere astrofisico?\, con un neanche troppo nascosto riferimento a un famoso quiz televisivo. \nCi sono poi molte attività che stimolano la parte artistica\, in particolare quella dei bambini\, come per esempi Il Solametro – Disegna i Pianeti e mettili al posto giusto\, o ancora Disegna il tuo pianeta (reale o immaginario) e un classico come Pixel Art\, ovviamente a tema astronomico. \nNell’Area Comics\, poi\, il 7 giugno alle 11 in sala Galatea Angelo Adamo\, ricercatore tecnologo dell’INAF IASF di Palermo\, presenta INAFfumètti: con la testa ben oltre le nuvole (balloons)\, nel corso del quale presenterà la sua ultima opera\, realizzata in collaborazione con Sandro Bardelli\, dell’OAS di Bologna. B.A.O. – Baryon-Acoustic-Oscillations\, che segue anche stilisticamente l’opera dello scorso anno\, presentata a Lucca Comics&Science 2023\, è incentrato sulla materia oscura ed è un’ottima introduzione alla scienza dietro Euclid\, il satellite dedicato proprio allo studio di questa sfuggente forma della materia.Ovviamente i lettori di EduINAF possono scaricare il fumetto a questo link: B.A.O. – Baryon-Acoustic-Oscillations. \nBuona lettura e una buona Etna Comics a chi andrà a visitare questa emozionante rassegna! \nFonte: EduINAF URL:https://www.oact.inaf.it/event/etna-comics-2024/

Its recovery is generally carried out by parametric and (semi) blind methods after removing several Galactic and extragalactic emissions. However\, in order to take into account their non-linear behaviors\, Machine Learning approaches such Neural Networks seem to be promising for that task. In this talk\, I will describe how they begin to be an alternative and reliable methods for recovering the Cosmic Microwave Background. \n  \nA few rules:— in case of large in-person attendance\, attendees may be asked to wear a face mask— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

Santi Cassisi\, INAF-Osservatorio Astronomico d’Abruzzo \nABSTRACT:One of most important issue in Astrophysics is the achievement of a robust understanding of the sequence of processes that contributed to the building up of the Milky Way. This is obviously important not only “on a local scale” in order to recover the history of formation and evolution of the Galaxy\, but also\, more in general\, for understanding the formation process of spiral galaxies. In the last decade\, the advent of high precision photometric and spectroscopic surveys as well as the possibility to estimate\, thanks to the ESA Gaia mission\, accurate distance for a huge number of field stars\, combined with the development of an accurate theoretical framework\, is actually opening a new era for this kind of investigations.We will present some recent results – obtained by using this updated observational and theoretical framework – about the formation and early evolution of the Milky Way. \n  \nA few rules:— in case of large in-person attendance\, attendees may be asked to wear a face mask— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

Orlando (School of Chemistry and Biochemistry and School of Physics\, Georgia Institute of Technology\, Atlanta\, GA\, USA) \nABSTRACT:It is well known that the interaction of energetic ions\, electrons and photons with surfaces and interfaces leads to non-thermal desorption via a process typically referred to as desorption induced by electronic transitions (DIET).  When DIET involves either electrons or photons\, these processes are generally referred to as electron-stimulated desorption and photon-stimulated desorption (PSD)\, respectively.  Recent attention has focused on understanding the role of non-thermal “space weathering” in the processing of interstellar grains and ices.Specifically\, there is deep interest in understanding the radiation processing of carbon grains in the solar nebula and unraveling the H2O formation mechanisms in solar nebula and planetary systems\, including the Moon. Using graphite grains\, the VUV photon-simulated oxidation of carbon grains via reactive scattering of water fragments produced by dissociative electron attachment at the buried interface was examined. The results suggested that VUV PSD at the buried water:carbon grain interface may help control the carbon inventory during planet formation. The inverse process\, (i.e\, the formation of water) may happen on metal-oxide samples such as mineral grains and lunar regolith samples\, that contain or are terminated by hydroxyl groups. Solar wind spaceweathering experiments of several Apollo lunar samples demonstrated that thermally activated recombinative desorption (RD) can be H2O sources [2\,3] and that electron-stimulated reactive scattering to produce water may also be occurring\, especially when the Moon is in the magnetopause[4].  RD can occur on a diurnal basis on the Moon and is prevalentduring meteoroid impacts. The latter is simulated by laser irradiation studies followed by state and velocity resolved detection of the produced water.  Finally\, evidence of space weathering and surface alteration has also been revealed using spatially resolved\, high-resolution nanoscale Fourier transform infrared imaging/spectroscopy correlated with photoluminescence (PL) on Apollo samples with different origins and history. \n[1]  J.

For young\, rapidly rotating B-stars that have not yet been spun down by wind-magnetic braking\, wind material can be trapped between the Kepler co-rotation radius (RK) and the Alfven radius (RA)\, forming then a “Centrifugal Magnetosphere” (CM)\, with density set at the critical level for “Centrifugal Breakout” (CBO) against the confining magnetic tension. This talk discusses how such CBO controls both the onset and strength of observed H-alpha emission\, while the energetics of the associated CBO-driven magnetic reconnection match well the observed scalings of a non-thermal\, circularly polarized radio emission from such stars . \n  \nA few rules:— in case of large in-person attendance\, attendees may be asked to wear a face mask— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

Alessio Traficante (IAPS-INAF) \nABSTRACT:The star formation mechanism occurs in well defined structures that can be identified and studied in great details in our own Galaxy: the process starts in giant molecular clouds\, objects extended up to several tens of parsecs\, within which elongated sub-structures\, called filaments\, may form. Inside filaments\, round-like condensations extended up to ~1pc in radius\, the so-called clumps\, are the natural birth site of the pre- and proto- stellar fragments\, inside which will origin the future stars.There are still many open questions in this hierarchical view of the star formation process: are these structures relatively confined from each other\,  or is the large-scale environment affecting the dynamics of the formation down to clumps and fragments? Is there a continuous interplay of the various forces involved in the process\, namely turbulence\, gravity (and magnetic fields)\, at all scales? Or is there a relevant scale at which gravity will start to dominate the collapse\, with critical implications on the star-formation mechanism?After a general overview of the problem\, I will present in details some recent results focused on the interplay between gravity and turbulence at the filament\, clump and fragment scales. To investigate this interplay at the larger scales\, we have combined the dynamics of so-called 70 micron quiet clumps\, i.e. very pristine regions not yet strongly affected by feedbacks\, with the dynamics of the parent filaments in which they are embedded. At smaller scales\, I will discuss the different scenarios of fragments formation in light of the most recent results from the SQUALO (Star formation in QUiescent And Luminous Objects) project. This ALMA survey has been designed to investigate the formation properties in a sample of massive clumps selected to be at various evolutionary stages and with the common feature that they are all accreting at the clump scales.Our results show that a large scales we observe a continuous interplay between turbulence and gravity\, where the former creates structures at all scales and the latter takes the lead above a critical value of the surface density is reached\, ~ 0.1 g cm^-2. At the same time\, the fragmentation properties show several indications that the fragment are “clump-fed”\, i.e. the process is dynamical and the gravity dominates the collapse inside our massive clumps. \n  \nA few rules:— in case of large in-person attendance\, attendees may be asked to wear a face mask— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE:  Thursday\, March 27\, 11:00 a.m. \nORGANIZER: INAF-OACT \nLOCATION: AULA OVEST (INAF-OACT) + remote \nLink for the remote audience:https://meet.google.com/wvf-uwxo-oyj \nSPEAKER: Dr. Eva Panetier (CEA Saclay\, Université Paris Cité) \nABSTRACT:Outside of solar neutrinos\, the only way to directly probing solar and stellar interiors is to use seismic techniques\, i.e. studying the waves propagating inside them. In the case of the Sun\, acoustic waves are excited by turbulent motion in the convective envelope\, and propagate towards the interior\, creating a variety of standing pressure modes (p modes). By investigating how small perturbations influence the modes parameters\, it is possible to probe the structural and dynamical properties of the star such as internal rotation and mixing\, chemical composition\, density\, convection zone depth\, etc. In the stellar case\, asteroseismology allows the inference of the stellar fundamental parameters such as mass\, radius\, and age. Although\, solar p-modes frequency\, amplitude\, and energy vary in relation with the solar magnetic cycle and similar variations were observed for other magnetically active solar-type stars\, such a variability is often overlooked in stellar modelling. In the context of the preparation of the PLATO mission\, whose aim is to characterize Earth-like planets orbiting solar-like stars in part thanks to asteroseismology\, we need to better understand the relation between magnetic variations and modes parameters. In this seminar\, I will focus on the excitation of the solar p modes using the last 28 years of data from the SoHO/GOLF instrument\, with a method gathering a better temporal resolution compared to classical approaches. In this framework\, I was able to perform a statistical study of the energy of the modes. Summing the energy of all studied modes\, I will demonstrate that there is a discrepancy between the observed excitation rate and the expected rate under the hypothesis of excitation driven entirely by turbulent convection. I will discuss the link between this discrepancy and surface magnetism effects such as flares and coronal mass ejection. In conclusion\, I will explain how a better understanding of the relation between the dynamo mechanism and modes properties variation across time would allow us to improve the constraint we have on stellar dynamics and obtained refined stellar fundamental parameters. \n  \nA few rules:— in case of large in-person attendance\, attendees may be asked to wear a face mask— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

Its highly chromatic nature imparts trends in the underlying spectrum that become most noticeable at shorter wavelengths due to the increased contrast between the flux from the active regions (i.e. spots and/or faculae) and the quiet photosphere. The second characteristic is that activity is inherently time-variable\, predominantly modulated by stellar rotation as active regions rotate into and out of view but also with contributions from longer timescales of evolution/decay and even long-term activity cycles e.g. maxima and minima (although certain configurations e.g. polar spots and active latitudes will be more resistant to this). This variability can reveal itself through subsequent observations of the system and is both useful and challenging; it can further help us to identify and constrain potential contamination but also means that observations at different epochs may require individual corrections before they can robustly be combined and analysed together which will become increasingly difficult for smaller planets as the SNR of each visit progressively decreases. In this seminar I will present how both diagnostics have been used with archival HST WFC3 and STIS datasets to create two new activity metrics that are highly complementary to existing indicators. I will also show preliminary results surrounding how this work is being extended to Tier 2 and Tier 3 Ariel simulations to explore how stellar variability will impact our ability to stack visits to obtain the required SNR for these tiers. \n  \nA few rules:— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

ESA’s Planck mission has observed CMB temperature anisotropies at the cosmic variance limit\, but polarisation remains to be further investigated. CMB polarisation data are important not only because they contribute to provide tighter constraints on cosmological parameters but also because they allow the study of physical processes that would be excluded if only the CMB temperature maps were considered. I use polarisation data into account to assess the statistical significance of the anomalies currently observed only in the CMB temperature map\, and to constrain the Cosmic Birefringence (CB) effect\, which is expected in parity-violating extensions of the standard electromagnetism.Measuring CMB polarisation is technically challenging because the polarised signal is much fainter than the temperature signal\, and accurate polarisation estimates require exquisite control of systematic effects. To investigate the impact of spurious signals in upcoming CMB polarisation experiments\, I present a study of the interplay between half-wave plate (HWP) non-idealities and the beams of the instrument for the next generation of CMB experiments\, with an insight into how this instrumental contamination affects the measurement of the cosmic birefringence effect. \n  \nA few rules:— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

A focus is put on tokamak edge and white dwarf atmosphere plasma conditions. In both cases\, the observed spectra exhibit clean lines\, either in absorption or in emission\, denoting the presence of neutral species (atoms). An analysis of the line shape and intensity yields information on the plasma parameters provided a suitable physical model is used. We first discuss in detail the physical mechanisms underlying the broadening of the spectral lines due to the plasma microfield (Stark effect)\, and we next report on models and codes that have been developed in our group at the PIIM laboratory. Applications to the fitting of observed spectra – both in magnetic fusion and astrophysics – are presented. Motivated by current research trends\, we also discuss specific issues related to the presence of strong external magnetic field (Zeeman effect etc.) and report on some recent works done in atomic physics for the improvement of line shape models. \n  \nA few rules:— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

Irfan (IoA\, University of Cambridge) \nABSTRACT:The next generation of Cosmic Microwave Background experiments are poised to probe the inflationary period of the Universe through the measurement of primordial B-modes\, whilst 21cm experiments are observing the reionization history of the early Universe and formation of Large-Scale Structure through the mapping of neutral hydrogen. These two complementary fields span the radio to microwave frequency regimes and share a pivotal data reduction task: foreground component separation.Diffuse Galactic synchrotron emission is the dominant foreground for arcmin/degree scale cosmological surveys operating across MHz frequencies in intensity\, and at all frequencies under 60 GHz in polarised intensity. In this talk I will present measurements of the synchrotron spectral index and curvature between 73 MHz and 1 GHz through the combined use of pilot MeerKLASS\, Haslam\, Maipu/MU and LWA data. I will discuss the advances that can be made to component separation algorithms thanks to more sophisticated foreground emission modelling and will present a spatially complex\, all-sky model of the synchrotron spectral index formed using convolutional neural networks trained on sets of both high- and low-resolution empirical data. Such advances will\, and already are\, expanding our understanding of the spatial and spectral form of this complex emission; ameliorating component separation for both CMB and 21cm intensity mapping experiments. \n  \nA few rules:— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.
