Resolved stellar populations as tracers of galaxy evolution
Giovedì 23 aprile alle ore 12:00 Matteo Monelli (INAF – Osservatorio Astronomico d’Abruzzo) terrà un seminario dal titolo “Resolved stellar populations as tracers of galaxy evolution“.
Abstract:
Resolved stellar populations in Local Group galaxies provide fundamental information to understand galaxy formation and evolution, which can be constrained using their photometric, spectroscopic, and dynamical properties. Pulsating variable stars such cepheids and RR Lyrae star add extra constraints, as they trace the age and metallicity of the parent population.
In this talk I will show how combining different approaches such as the star formation history derivation from the deep colour-magnitude diagrams together with the properties of variable stars can provide quantitative insights on the host galaxy evolution, chemical evolution, and accretion history. In the era of large photometric and spectroscopic surveys, pulsating stars will thus be crucial to investigate all the Galactic structures, from the obscured bulge and disk to the most remote parts of the halo, as well as nearby dwarf systems to the outskirts of the Local Group.
