Effects of Rotation on Mass Loss for Population III stars
Sylvia Ekström, Georges Meynet, André Maeder
Abstract
The effects of rotation on low-metallicity stellar models are twofold: first, the models reach break-up during main sequence and may lose mass by mechanical process; second, strong internal mixing brings freshly synthesized elements towards the surface and raises the effective metallicity to higher values, so that the initially very low radiative winds are enhanced. Those two effects are also found in Z=0 models, but to a lesser degree because of structural differences. This weak mass loss becomes interesting though in the case of the black hole-doomed stars (25-140 M and > 260 M) because it allows these stars to contribute to the enrichment of the medium by stellar winds.
