New P30(p,γ)S31 resonances and oxygen-neon nova nucleosynthesis
Abstract
Enriched isotopic abundance ratios of Si30/Si28 in several presolar SiC and graphite grains qualitatively indicate massive oxygen-neon (ONe) nova origins but fall short of hydrodynamic ONe nova model ejecta predictions by as much as an order of magnitude. The astrophysical P30(p,γ)S31 reaction rate uncertainty at ONe nova temperatures (0.10
