Description
A new nucleosynthesis process, that we denote $\nu p$-process, will be presented. It
occurs in supernovae (and possibly gamma-ray bursts) when strong neutrino fluxes
create proton-rich ejecta. In this process, antineutrino absorptions in the
proton-rich environment produce neutrons that are immediately captured by
neutron-deficient nuclei. This allows for the nucleosynthesis of nuclei with mass
numbers $A>64$. Making this process a possible candidate to explain the origin of the
solar abundances of the light p-nulcei (such as $^{92,94}$Mo and $^{96,98}$Ru). This
process also offers a natural explanation for the large abundance of Sr seen in an
hyper-metal-poor star.
