Description
I will review the presupernova evolution and the associated explosive
nucleosynthesis of massive stars with mass loss in the mass interval between 11 and
120 Msun. For the solar metallicity models i will address the following topics: 1)
the evolutionary properties of Wolf-Rayet stars and their comparison with
observations; 2) the chemical yields provided by a generation of core collapse
supernovae; 3) the contribution of these stars to the production of Al26 and Fe60
in
the Galaxy. For the zero metallicity models i will mainly disucuss their chemical
yields and their connection with "normal" and C-rich extremely metal poor stars.
