Problems in the Chemical Evolution of Galaxies

1984
The chemical evolution of a galaxy is governed by the evolution of individual stars as well as collective processes such as star formation rate, stellar mass function and dynamics of the gas-stars system. Such a problem has been the subject of a great deal of work as reported in many up to date reviews, among which we recall Tinsley (1980), Pagel and ...

Nucleosynthesis and Chemical Evolution of Galaxies

1983
This chapter deals with a brief presentation of the nucleosynthesis processes which are responsible for the formation of the observed chemical elements : the primordial nucleosynthesis occurring just after the Big Bang, responsible for the formation of D, 3He,4 He and at least in part 7Li; the bombardment of the interstellar medium by galactic cosmic ...

Chemical Evolution of Irregular Galaxies

2011
In this chapter, we describe the properties of irregular galaxies and the proposed chemical evolution models. Irregular galaxies are generally small and rather simple objects with low metallicity and large gas content, suggesting that they are either young objects or have undergone discontinuous star formation activity (bursts) or a continuous but not ...
