Presupernova evolution and explosion of massive stars with mass loss
  We review the main properties of solar metallicity massive stars in the range 11-120 Msun. The influence of the mass loss on the hydrostatic burning stages as well as the final explosion is discussed in some detail. We find that the minimum masses that enter the WNL, WNE and WC stages are 30 Msun, 35 Msun and 40 Msun respectively; the limiting mass between stars exploding as SNII and SNIb/c is between 30 and 35 Msun; the limiting mass between stars forming neutron stars and black holes after the explosion is between 25-30 Msun. We also discuss the properties of the chemical yields integrated over a Salpeter IMF and we find that stars with M>=35 Msun contribute for ~60% to the production of C, N and for ~40% to the production Sc and s-process elements up to Zr, while they do not produce any intermediate mass element because of the large remnant masses
