A Long, Cold, Early r-process? Neutrino-induced Nucleosynthesis in He Shells Revisited

P. Banerjee, W. C. Haxton, Y. -Z. Qian

We revisit a neutrino-driven r-process mechanism in the He shell of a core-collapse supernova, finding that it could succeed in early stars of metallicity < solar/1000, at relative…
