Explosive Nucleosynthesis in Core Collapse Supernovae — •Carla Frohlich — The University of Chicago, Chicago IL, USA
Recent advances in core collapse supernova nucleosynthesis are presented, in particular the production of heavy elements by the ν p-process and the r-process. Modern hydrodynamical simulations of core collapse supernovae show proton-rich ejecta which are subject to strong (anti-) neutrino fluxes. Antineutrino captures catalyze the synthesis of nuclei with mass number A>64 (ν p-process). Core collapse supernovae are also considered as a possible site for the r-process, in particular at later times when the ejecta become neutron-rich.
