P-process nucleosynthesis during He-detonation in sub-Chandrasekhar CO white dwarfs
Abstract
He-accreting white dwarfs with sub-Chandrasekhar mass are revisited. It is shown that the considered scenario can be the site of an αp-process combined with a p-process and with a variant of the rp-process we refer to as the pn-process. We define the conditions under which the derived distribution of the abundances of the p-nuclides in the ejecta, including the puzzling light Mo and Ru isotopes, mimics the solar-system one.
