Nucleosynthesis in core-collapse supernova explosions triggered by a quark-hadron phase transition
Nishimura, Nobuya; Fischer, Tobias; Thielemann, Friedrich-Karl; Froehlich, Carla; Hempel, Matthias; Kaeppeli, Roger; Martinez-Pinedo, Gabriel; Rauscher, T.; Sagert, Irina; Winteler, Christian (2012-10-10)We explore heavy-element nucleosynthesis in the explosion of massive stars that are triggered by a quark-hadron phase transition during the early post-bounce phase of core-collapse supernovae. The present study is based ... -
The s-Process Nucleosynthesis in Low Mass Stars : Impact of the Uncertainties in the Nuclear Physics Determined by Monte Carlo Variations
Cescutti, Gabriele; Hirschi, Raphael; Nishimura, Nobuya; Rauscher, Thomas; den Hartogh, Jacqueline; Murphy, Alex St J.; Cristallo, Sergio (Springer Nature, 2019-08-20)We investigated the impact of uncertainties in neutron-capture and weak reactions (on heavy elements) on the s-process nucleosynthesis in low-mass stars using a Monte-Carlo based approach. We performed extensive nuclear ... -
Uncertainties in s-process nucleosynthesis in massive stars determined by Monte Carlo variations
Nishimura, Nobuya; Hirschi, Raphael; Rauscher, Thomas; Murphy, Alexander St J.; Cescutti, Gabriele (2017-08-01)The $s$-process in massive stars produces the weak component of the $s$-process (nuclei up to $A \sim 90$), in amounts that match solar abundances. For heavier isotopes, such as barium, production through neutron capture ... -
Uncertainties in the Production of p Nuclides in SN Ia Determined by Monte Carlo Variations
Rauscher, Thomas; Nishimura, Nobuya; Hirschi, Raphael; Murphy, Alex St J.; Cescutti, Gabriele; Travaglio, Claudia (Springer Nature, 2019-08-20)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 from nuclear physics uncertainties in the ...
