Capuano (University of Catania\, Department of Physics and Astronomy ”Ettore Majorana”\, and INAF – OACT) \nABSTRACT:The solar corona has been investigated in the last decades through observations coming from several spacecraft. The Metis coronagraph\, aboard the ongoing Solar Orbiter mission\, extends the UVCS/SOHO spectrocoronagraph observations of the scattered ultraviolet emission of the coronal plasma performed during solar activity cycle 23\, by simultaneously imaging the coronal visible light polarised brightness (VL pB)\, in the spectral bandpass 580-640 nm\, and the coronal ultraviolet H I Lyα emission\, in the spectral window 121.6 ± 10 nm. Here some specific observations are shown\, such as those taken on May 15\, 2020\, from which important results about the solar wind outflow velocity were inferred by applying the Doppler dimming technique. Other results on the coronal solar wind velocity are presented\, obtained by considering the data acquired during the first quadrature of the Solar Orbiter and the Parker Solar Probe (PSP) spacecraft with respect to the Sun. In particular\, the same parcel of plasma on the East limb was remotely observed with Metis between 3.5 R⊙ and 6.3 R⊙ on January 17\, 2021\, during low-cadence synoptic mode observations\, and was sampled in situ by PSP at about 22 R⊙ on January 18\, 2021. In this case\, information about several coronal parameters were inferred with unprecedented details\, thanks to the high quality of Metis and PSP data. Finally\, other results concerning the first coronal mass ejection observed with Metis on January 16-17\, 2021 are reported. In this case\, also considering data coming from instruments onboard Solar Orbiter and other spacecraft\, a 3D reconstruction and detailed physical information about this structure were obtained. Therefore\, Metis\, even when operates in synoptic mode and in synergistic coupling with other instruments\, allows to get novel and detailed information about the structure of the solar corona with an accuracy never reached until now.

Sussman (Universidad Nacional Autónoma de México) \nABSTRACT:I would like to summarize and present cosmological applications of two proposals of Gravitational entropy\, which are distinct from the standard holographic approach and from the entropy of the sources. One is the proposal by Clifton-Ellis and Tabakol (CET) based on the Bel-Robinson tensor\, the other by Hosoya and Buchert (HB)\, based on the Leibler-Kullbach functional of Information Theory. By applying these proposals to inhomogenous dust solutions of Einstein’s equations (LTB and Szekeres models)\, we have shown in various published articles that both proposals are equivalent in their predictions\, but CET is local and HB is non-local. Both yield entropy production in spacetime regions that can be characterized by generation and growth of structure (either overdensities or voids). The CET proposal provides an interesting interpretation of the cosmological constant as an asymptotic gravitational temperature that characterizes a finite entropy saturation value. \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.

Gabriel Ferrero (University of La Plata\, Argentina) \nABSTRACT:Massive stars (i.e. the progenitors of core-collapse supernovae) are quite scarce\, but play a crucial role in several important astrophysical phenomena\, as for example\, the chemical evolution of their host galaxies. Even so\, their fundamental stellar parameters (as mass\, radii\, temperature and luminosity) are poorly known. This relates to important uncertainties about their formation processes\, structure and evolution. We are attempting  to face this challenge at the research group GEMAE (Grupo de investigación en Estrellas Masivas y Agrupaciones Estelares) at the University of La Plata\, together with collaborators in Chile and Spain. We rely mainly on high-quality and high-resolution spectroscopic data collected by 18 years by the OWN Survey of the O-type and WN-stars in the Southern hemisphere. In this talk I will outline the work that we are developing at GEMAE\, focusing on determinations of masses of close binary stars by spectroscopy and photometry in the optic and near-infrared bands. \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.
