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…
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…
Is γ-ray emission from novae affected by interference effects in the 18F(p,α)15O reaction?
A. M. Laird, A. Parikh, A. St. J. Murphy +14
The 18F(p,α)15O reaction rate is crucial for constraining model predictions of the γ-ray observable radioisotope 18F produced in novae. The determination of this rate is challengin…
