Description

In massive stars evolution the s-process is activated at different temperatures, during He-burning and during C-burning. In the convective C Shell, the s-process affects the previous Core He-burning s yields, and the final results carry the signature of both the two following neutron capture processes. A detailed analysis of the s-process in massive stars is presented, in particular at the end of the Shell C-burning when the local temperature could rapidly increase with the s-process efficiency.
