The chemical evolution of the Galaxy : the importance of stars with an initial mass larger than 40 M ⊙

Abstract

In the present paper we investigate in how far stars with an initial mass larger than 40M ⊙ affect the chemical enrichment of the Galaxy. We illustrate the importance for chemical yields of a most up to date treatment of the various stellar wind mass loss episodes in stellar evolutionary codes and we discuss the effects of a possible supernova-like outburst… (More)
