Stellar yields as a function of initial metallicity and mass limit for black hole formation

摘要: Grids of evolutionary star models from 1 to 120 M ⊙ with metallicities Z = 0.001 and 0.020 are used derive chemical yields for studies on the evolution galaxies. The stellar include new opacities by Rogers & Iglesias (1992) take into account, in addition usual metal dependent opacity nuclear effects, changes mass loss rates metallicity predicted wind also dependence WR stars their actual masses. Moderate core overshooting is accounted
