Query: Nucleosynthesis in neutrino heated matter: The vp-process and the
  r-process   This manuscript reviews recent progress in our understanding of the
nucleosynthesis of medium and heavy elements in supernovae. Recent
hydrodynamical models of core-collapse supernovae show that a large amount of
proton rich matter is ejected under strong neutrino fluxes. This matter
constitutes the site of the vp-process where antineutrino absorption reactions
catalyze the nucleosynthesis of nuclei with A > 64. Supernovae are also
associated with the r-process responsible for the synthesis of the heaviest
elements in nature. Fission during the r-process can play a major role in
determining the final abundance patter and in explaining the almost universal
features seen in metal-poor r-process-rich stars.
