Nucleosynthesis simulations for the production of the p-nuclei ${}^{\text{92}}$Mo and ${}^{\text{94}}$Mo in a Supernova type II model

Abstract

We present a nucleosynthesis sensitivity study for the $\gamma$-process in a Supernova type II model within the NuGrid research platform. The simulations aimed at identifying the relevant local production and destruction rates for the p-nuclei of molybdenum and at determining the sensitivity of the final abundances to these rates. We show that local destruction rates strongly determine the abundance of ${}^{92}$Mo and ${}^{94}$Mo, and quantify the impact.
