Massive stars in the range 13-25 M⊙:: Evolution and nucleosynthesis.: II.: The solar metallicity models

We present the evolutionary properties of a set of massive stellar models (namely 13, 15, 20, and 25 M-circle dot) 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 Zn-68 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.
