Abstract: (arXiv)
We present the \nuk{Al}{26} and \nuk{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 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 \nuk{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 \nuk{Fe}{60} yield as well. From these computations we conclude that, at variance with current beliefs, \nuk{Al}{26} is mainly produced by the explosive C/Ne burning over most of the mass interval presently analyzed while \nuk{Fe}{60} is mainly produced by the C convective shell and the He convective shell.References(59)
