SUMMARY:Unraveling Space Weathering on Planetary and Astrophysical Surfaces
DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE:  Friday\, October 4\, 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: Prof. Thomas M. 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.

SUMMARY:Stellar-wind-fed magnetospheres of magnetic massive stars
DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE:  Monday\, October 21\, 11:30 a.m. \nORGANIZER: INAF-OACT \nLOCATION: AULA OVEST (INAF-OACT) + remote \nLink for the remote audience:https://meet.google.com/wvf-uwxo-oyj \nSPEAKER: Prof. Stanley Owocki (University of Delaware) \nABSTRACT:A subpopulation (~9%) of hot (OB) stars exhibit strong (B~100-10\,000 G)\, large-scale (often predominantly dipolar) magnetic fields that channel their stellar wind outflows into circumstellar magnetospheres. 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.

SUMMARY:Spectroscopic observations and modeling of solar flares: new insights from IRIS
DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE:  Wednesday\, October 30\, 10:30 a.m. \nORGANIZER: INAF-OACT \nLOCATION: AULA OVEST (INAF-OACT) + remote \nLink for the remote audience:https://meet.google.com/wvf-uwxo-oyj \nSPEAKER: Vanessa Polito (Lockheed Martin Solar and Astrophysics Laboratory) \nABSTRACT:Recent high-resolution observations from the IRIS satellites have enabled significant advancements in our understanding of the physical mechanisms at play during the impulsive phase of flares\, including details of how the non-thermal energy is released and propagated from the corona to the low-atmosphere through accelerated particles. At the same time\, the new discoveries have brought to light new unsolved questions and challenges for current models. This talk will provide some examples of the unique contributions to our understanding of flares from IRIS\, also in coordination with other solar observatories\, and how state-of-the-art heating models of flares can be constrained by the available imaging and spectral diagnostics. I will also discuss some of the outstanding problems in preparation for the next generation of solar missions. \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.
