A Comparison of Chemical Evolution between the Milky Way and M31 Galaxy

The Chemical Evolution of the Milky Way

The Evolution of Isotope Ratios in the Milky Way Galaxy

Isotope ratios have opened a new window into the study of the details of stellar evolution, supernovae, and galactic chemical evolution. We present the evolution of the isotope ratios of elemental abundances (from C to Zn) in the solar neighbourhood, bulge, halo, and thick disk, using chemical evolution models with updated yields of Asymptotic Giant Branch (AGB) stars and core-collapse supernov...

Chemical evolution of the Milky Way and its Satellites

1 How to model galactic chemical evolution Before going into the detailed chemical evolution history of the Milky Way and its satellites, it is necessary to understand how to model, in general, galactic chemical evolution. The basic ingredients to build a model of galactic chemical evolution can be summarized as : • Initial conditions; • Stellar birthrate function (the rate at which stars are f...
