Terzo appuntamento del secondo semestre con i seminari di Dipartimento 2024-2025
Per i seminari del Dipartimento di Scienze Fisiche e Chimiche Mercoledì 26 Marzo alle ore 14.30 in aula A.1.6 (Edificio "Renato Ricamo") il Dott. Santi Cassisi (INAF – Osservatorio Astronomico d’Abruzzo) terrà un seminario dal titolo
"Galactic Archaeology: decoding the fossil record of the Milky Way formation and evolution
Abstract
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" 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 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. In the same time, it will be emphasized the crucial role played by updated stellar evolution models for dating field and cluster stars, a pivotal step for any Galactic archeology investigations.
