 Galactic astroarchaeology:chemical abundances and evolution of galaxies

 

 ABSTRACT

The basic principles and ingredients for modeling the chemical evolution of galaxies will be discussed. We will show how models of chemical evolution of galaxies can allow us to predict the evolution of chemical abundances in gas and stars and how the comparison between model predictions and observational data enable us to impose constraints on the history of star formation and stellar nucleosynthesis. What we call astroarchaeology is the reconstruction of galaxy evolution by means of chemical abundances. In the framework of the astroarchaeological approach we will discuss the role of different stars in the galactic chemical enrichment and in particular the role of SNe of different type (II, Ia, Ib, Ic). The chemical evolution of the different components of the Milky Way (halo, bulge, thick and thin disk), as well as dwarf spheroidals and ultra-faint dwarfs of the Local Group, will be presented and some conclusions will be drawn.
