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 the production of p nuclides in SN Ia determined by Monte Carlo variations
T. Rauscher, N. Nishimura, R. Hirschi +3
Several thousand tracers from a 2D model of a thermonuclear supernova were used in a Monte Carlo post-processing approach to determine p-nuclide abundance uncertainties originating…
Production Uncertainties of p-Nuclei in the -Process in Massive Stars Using a Monte Carlo Approach
T. Rauscher, N. Nishimura, R. Hirschi +3
Proton-rich nuclei, the so-called p-nuclei, are made in photodisintegration processes in outer shells of massive stars in the course of the final supernova explosion. Nuclear uncer…
Uncertainties in the production of nuclei in massive stars obtained from Monte Carlo variations
T. Rauscher, N. Nishimura, R. Hirschi +3
Nuclear uncertainties in the production of nuclei in massive stars have been quantified in a Monte Carlo procedure. Bespoke temperature-dependent uncertainties were assigned to…
