3D simulations of a complete convective silicon shell burning phase
V. Varma, R. Hirschi, F. Rizzuti +7
We present 3D hydrodynamic simulations of a complete silicon shell burning phase until fuel exhaustion at the end of the evolution of a 14 core-collapse supernova progenit…
Extension of the particle x-ray coincidence technique: The lifetimes and branching ratios apparatus
L. J. Sun, J. Dopfer, A. Adams +11
The particle x-ray coincidence technique (PXCT) was originally developed to measure average lifetimes in the ~s range for proton-unbound states populated by elec…
Shell mergers in the late stages of massive star evolution: new insight from 3D hydrodynamic simulations
Federico Rizzuti, Raphael Hirschi, Vishnu Varma +6
One-dimensional (1D) stellar evolution models are widely used across various astrophysical fields, however they are still dominated by important uncertainties that deeply affect th…
3D simulations of convective shell Neon-burning in a massive star
C. Georgy, F. Rizzuti, R. Hirschi +6
The treatment of convection remains a major weakness in the modelling of stellar evolution with one-dimensional (1D) codes. The ever increasing computing power makes now possible t…
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 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…
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…
Role of core-collapse supernovae in explaining Solar System abundances of p nuclides
C. Travaglio, T. Rauscher, A. Heger +2
The production of the heavy stable proton-rich isotopes between 74Se and 196Hg -- the p nuclides -- is due to the contribution from different nucleosynthesis processes, activated i…
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…
