Fission cycling in supernova nucleosynthesis: Active-sterile neutrino oscillations
We investigate nucleosynthesis in the supernova post-core bounce neutrino-driven wind environment in the presence of active-sterile neutrino transformation. We consider active-sterile neutrino oscillations for a range of mixing parameters: vacuum mass-squared differences of $0.1\text{ }\text{ }{\mathrm{eV}}^{2}\ensuremath{\le}\ensuremath{\delta}{m}^{2}\ensuremath{\le}100\text{ }\text{ }{\mathrm{eV}}^{2}$, and vacuum mixing angles of ${sin}^{2}2{\ensuremath{\theta}}_{v}\ensuremath{\ge}{10}^{\ensuremath{-}4}$. We find a consistent $r$-process pattern …
