The nucleosynthesis of Al26 and Fe60 in solar metallicity stars extending in mass from 11 to 120 Msun: the hydrostatic and explosive contributions
Abstract
We present the Al26 and Fe60 yields produced by a generation of solar metallicity stars ranging in mass between 11 and 120. We discuss the production sites of these γ ray emitters and quantify the relative contributions of the various components. More specifically we provide the separate contribution of the wind, the C convective shell and the explosive Ne/C burning to the total Al26 yield per each stellar model in our grid. We provide the contributions of the He convective shell, the C convective shell and the explosive Ne/C burning to the Fe60 yield as well. From these computations we conclude that, at variance with current beliefs, Al26 is mainly produced by the explosive C/Ne burning over most of the mass interval presently analyzed while Fe60 is mainly produced by the C convective shell and the He convective shell.
