We have the pleasure to host the next Infinite Horizons' seminar on November 20th, 2024. Our host will be Prof. Alessandro Bemporad from the INAF-Astrophysical Observatory of Turin. Prof. Bemporad will talk about Studying the Solar Corona with Total Solar Eclipses.
Seminar's abstract:
Total solar eclipses still constitute a unique opportunity to observe and study from a scientific point of view the innermost region of the sun's tenuous atmosphere, the solar corona. Two total solar eclipses have recently occurred, both visible from the United States of America, therefore an easily accessible site. In this seminar, after a brief introduction on some of the problems still open in the study of the solar corona, I will describe the observations that I acquired in particular during the two total eclipses of 21 August 2017 and 8 April 2024. In particular, the analysis of the polarized observations acquired during the 2017 eclipse made it possible not only to derive the density of the solar corona, but also to test a new methodology never considered before for the derivation of the intensity of the coronal magnetic fields. The data acquired during the 2024 eclipse have yet to be analyzed, but during the seminar a preliminary analysis of images acquired at very high frequency with a polarized camera (PolarCam) will be also illustrated.

About the speaker:
Alessandro Bemporad is currently associate researcher at the INAF-Astrophysical Observatory of Turin, Italy. After obtaining a Master's Degree in Physics in 2002 and a Ph.D in Astrophysics in 2005 both at the INAF-Astrophysical Observatory of Florence, in 2007 he moved to the INAF-Astrophysical Observatory of Turin where he obtained the position of staff researcher in 2011, and then associate researcher from 2024. Since 2012 he has also held the role of contract university professor at the University of Turin where he holds a course on "Heliophysics and space weather". During his career he has mainly been involved in the analysis of visible light coronagraphic images and EUV spectroscopic observations acquired from space, aimed at studying the solar corona and in particular coronal mass ejections and prominence eruptions. He is currently involved in the ESA Solar Orbiter missions (and works mainly on Metis coronagraph data), and the ESA PROBA-3 mission, as well as numerous other fundamental research projects. He is also the PI of the space weather project SWELTO - Space Weather Lab in Turin Observatory.
