Uncertainties in the production of iron-group nuclides in core-collapse supernovae from Monte Carlo variations of reaction rates
Nobuya Nishimura, Carla Froehlich, Thomas Rauscher
Core-collapse supernovae, occurring at the end of massive star evolution, produce heavy elements, including those in the iron peak. Although the explosion mechanism is not yet full…
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…
The s-process nucleosynthesis in low mass stars: impact of the uncertainties in the nuclear physics determined by Monte Carlo variations
G. Cescutti, R. Hirschi, N. Nishimura +4
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 a…
Uncertainties in s-process nucleosynthesis in low mass stars determined from Monte Carlo variations
G. Cescutti, R. Hirschi, N. Nishimura +4
The main s-process taking place in low mass stars produces about half of the elements heavier than iron. It is therefore very important to determine the importance and impact of nu…
Sensitivity to neutron captures and beta-decays of the enhanced s-process in rotating massive stars at low metallicities
N. Nishimura, R. Hirschi, T. Rauscher
The s-process in massive stars, producing nuclei up to , has a different behaviour at low metallicity if stellar rotation is significant. This enhanced s-process is di…
Impacts of nuclear-physics uncertainties in the s-process determined by Monte-Carlo variations
N. Nishimura, G. Cescutti, R. Hirschi +3
The s-process, a production mechanism based on slow-neutron capture during stellar evolution, is the origin of about half the elements heavier than iron. Abundance predictions for…
Uncertainties in the production of p nuclides in thermonuclear supernovae determined by Monte Carlo variations
N. Nishimura, T. Rauscher, R. Hirschi +3
Thermonuclear supernovae originating from the explosion of a white dwarf accreting mass from a companion star have been suggested as a site for the production of nuclides. Such…
Abundance Uncertainties Obtained With the PizBuin Framework For Monte Carlo Reaction Rate Variations
T. Rauscher, N. Nishimura, G. Cescutti +2
Uncertainties in nucleosynthesis models originating from uncertainties in astrophysical reaction rates were estimated in a Monte Carlo variation procedure. Thousands of rates were…
The s-process nucleosynthesis: impact of the uncertainties in the nuclear physics determined by Monte Carlo variations
G. Cescutti, N. Nishimura, R. Hirschi +3
We investigated the impact of uncertainties in neutron-capture and weak reactions (on heavy elements) on the s-process nucleosynthesis in low-mass stars and massive stars using a M…
Impacts of nuclear-physics uncertainty in stellar temperatures on the s-process nucleosynthesis
N. Nishimura, G. Cescutti, R. Hirschi +3
We evaluated the uncertainty relevant to s-process nucleosynthesis using a Monte-Carlo centred approach. We are based on a realistic and general prescription of temperature depende…
Uncertainties in s-process nucleosynthesis in massive stars determined by Monte Carlo variations
Nobuya Nishimura, Raphael Hirschi, Thomas Rauscher +2
The -process in massive stars produces the weak component of the -process (nuclei up to ), in amounts that match solar abundances. For heavier isotopes, such as ba…
The r-process nucleosynthesis in the various jet-like explosions of magnetorotational core-collapse supernovae
Nobuya Nishimura, Tomoya Takiwaki, Friedrich-Karl Thielemann
The r-process nucleosynthesis in core-collapse supernovae (CC-SNe) is studied, with a focus on the explosion scenario induced by rotation and strong magnetic fields. Nucleosynthesi…
Code dependencies of pre-supernova evolution and nucleosynthesis in massive stars: Evolution to the end of core helium burning
Samuel Jones, Raphael Hirschi, Marco Pignatari +5
Massive stars are key sources of radiative, kinetic, and chemical feedback in the universe. Grids of massive star models computed by different groups each using their own codes, in…
Production of all the r-process nuclides in the dynamical ejecta of neutron star mergers
Shinya Wanajo, Yuichiro Sekiguchi, Nobuya Nishimura +3
Recent studies suggest that binary neutron star (NS-NS) mergers robustly produce the heavy r-process nuclei above the atomic mass number A ~ 130 because of their ejecta consisting…
Magnetorotationally driven Supernovae as the origin of early galaxy -process elements?
Christian Winteler, Roger Kaeppeli, Albino Perego +5
We examine magnetorotationally driven supernovae as sources of -process elements in the early Galaxy. On the basis of thermodynamic histories of tracer particles from a three-di…
Impact of New beta-decay Half-lives on r-process Nucleosynthesis
Nobuya Nishimura, Toshitaka Kajino, Grant J. Mathews +2
We investigate the effects of newly measured beta-decay half-lives on r-process nucleosynthesis. These new rates were determined by recent experiments at the radioactive isotope be…
