The Nucleosynthesis of 26 Al and 60 Fe in Solar Metallicity Stars Extending in Mass from 11 to 120 M ⊙ : The Hydrostatic and Explosive Contributions

Abstract

We present the uk{Al}{26} and uk{Fe}{60} yields produced by a generation of solar metallicity stars ranging in mass between 11 and 120\msun. We discuss the production sites of these $\gamma$ 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 uk{Al}{26} 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 uk{Fe}{60} yield as well. From these computations we conclude that, at variance with current beliefs, uk{Al}{26} is mainly produced by the explosive C/Ne burning over most of the mass interval presently analyzed while uk{Fe}{60} is mainly produced by the C convective shell and the He convective shell.
