| 内容記述 | We calculate Galactic Chemical Evolution (GCE) of Mo and Ru by taking into account the contribution from neutrino p-process nucleosynthesis. We estimate yields of p-nuclei such as 92;94Mo and 96;98Ru through the neutrino p-process in various supernova (SN) progenitors based upon recent models. In particular, the neutrino p-process in energetic hypernovae produces a large amount of p-nuclei compared to the yield in ordinary core-collapse SNe. We find that the neutrino p-process in hypernovae is the main contributor to the elemental abundance of 92Mo at low metallicity [Fe/H] < 2. Our theoretical prediction of the elemental abundances in metal-poor stars becomes more consistent with observational data when the neutrino p-process in hypernovae is taken into account. |
