r-Process enrichment in the Galactic halo characterized by nucleosynthesis variation in the ejecta of coalescing neutron star binaries
Takuji Tsujimoto, Nobuya Nishimura, Koutarou Kyutoku
A large star-to-star variation in the abundances of r-process elements, as seen in the [Eu/Fe] ratio for Galactic halo stars, is a prominent feature that is distinguishable from ot…
Impact of Uncertainties in Astrophysical Reaction Rates on Nucleosynthesis in the Process
T. Rauscher, N. Nishimura, G. Cescutti +3
The process appears in proton-rich, hot matter which is expanding in a neutrino wind and may be realised in explosive environments such as core-collapse supernovae or in outfl…
Impact of Uncertainties in Nuclear Reaction Cross Sections on p-Nucleosynthesis in Thermonuclear Supernovae
T. Rauscher, N. Nishimura, G. Cescutti +3
The propagation of uncertainties in reaction cross sections and rates of neutron-, proton-, and alpha-induced reactions into the final isotopic abundances obtained in nucleosynthes…
Uncertainties in p-process nucleosynthesis from Monte Carlo variation of reaction rates
N. Nishimura, T. Rauscher, R. Hirschi +3
It has been suggested that a p process can occur when hot, dense, and proton-rich matter is expanding within a strong flux of anti-neutrinos. In such an environment, proton-rich…
