Massive Stars in the Range 13–25 M ⊙ : Evolution and Nucleosynthesis. II. The Solar Metallicity Models

Abstract

We present the evolutionary properties of a set of massive stellar models (namely 13, 15, 20, and 25 M⊙) from the main-sequence phase up to the onset of the iron core collapse. All these models have initial solar chemical composition, i.e., Y = 0.285 and Z = 0.02. A 179 isotope network, extending from neutron up to 68Zn and fully coupled to the evolutionary code has been adopted from the carbon burning onward. Our results are compared, whenever possible, to similar computations available in literature.
