A combined study of thermohaline mixing and envelope overshooting with PARSEC: Calibration to NGC 6397 and M4
C. T. Nguyen, A. Bressan, A. J. Korn +7
Thermohaline mixing is one of the main processes in low-mass red giant stars that affect the transport of chemicals and, thus, the surface abundances along the evolution. The inter…
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…
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…
