Stellar chemical evolution

Stellar Yields and Chemical Evolution

Several speakers at this symposium have alluded to the zeroth-order agreement between the Type II supernovae (SNe) stellar yields, as predicted by the models of those most responsible for driving progress in the field i.e. Arnett (1991,1996); Maeder (1992); Woosley & Weaver (1995); Langer & Henkel (1995); Thielemann et al. (1996), hereafter referred to as A91, A96, M92, WW95, LH95, and TNH96, r...

Chemical element transport in stellar evolution models

Stellar evolution computations provide the foundation of several methods applied to study the evolutionary properties of stars and stellar populations, both Galactic and extragalactic. The accuracy of the results obtained with these techniques is linked to the accuracy of the stellar models, and in this context the correct treatment of the transport of chemical elements is crucial. Unfortunatel...

Chemical evolution models with a new stellar nucleosynthesis

Numerical models for the chemical evolution of the Galaxy have been computed with the new stellar yields published by Maeder (1992). These metallicity dependent yields represent an important improvement in the chemical evolution of galaxies but there are still uncertainties in the stellar evolution which prevent completely satisfactory results. From the comparison of the model predictions with ...

Stellar Populations and Chemical Evolution of Late–Type Dwarf Galaxies

Some aspects of the chemical evolution of late-type dwarf galaxies are reviewed, together with their implications on some issues of cosmological relevance. A more detailed approach to model their evolution is suggested. The importance of deriving the star formation history in these systems by studying their resolved stellar populations is emphasized.
