Trans-Fe elements from Type Ia Supernovae. I. Heavy element nucleosynthesis during the formation of near-Chandrasekhar white dwarfs
Umberto Battino, James Keegans, Megan Allen +9
Type Ia supernovae (SNIa) are thermonuclear explosions of white dwarfs in binary systems. They are central to galactic chemical evolution and serve as standardizable candles in cos…
Grids of stellar models with rotation VIII: Models from 1.7 to 500 at metallicity
Yves Sibony, Kendall G. Shepherd, Norhasliza Yusof +12
Grids of stellar evolution models with rotation using the Geneva stellar evolution code (Genec) have been published for a wide range of metallicities. We introduce the last remaini…
Very massive star winds as sources of the short-lived radioactive isotope Al
S. Martinet, G. Meynet, D. Nandal +7
The Al short-lived radioactive nuclide is the source of the observed galactic diffuse -ray emission at 1.8 MeV. While different sources of Al have been explored, s…
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…
NuGrid stellar data set - III. Updated low-mass AGB models and s-process nucleosynthesis with metallicities Z=0.01, Z=0.02 and Z=0.03
Umberto Battino, Ashley Tattersall, Claudia Lederer-Woods +6
The production of the neutron-capture isotopes beyond iron that we observe today in the solar system is the result of the combined contribution of the r-process, the s- process and…
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…
Production Uncertainties of p-Nuclei in the -Process in Massive Stars Using a Monte Carlo Approach
T. Rauscher, N. Nishimura, R. Hirschi +3
Proton-rich nuclei, the so-called p-nuclei, are made in photodisintegration processes in outer shells of massive stars in the course of the final supernova explosion. Nuclear uncer…
Linking 1D Evolutionary to 3D Hydrodynamical Simulations of Massive Stars
Andréa Cristini, Casey Meakin, Raphael Hirschi +3
Stellar evolution models of massive stars are important for many areas of astrophysics, for example nucleosynthesis yields, supernova progenitor models and understanding physics un…
Theory Considerations For Nucleosynthesis Beyond Fe With Special Emphasis On p-Nuclei In Massive Stars
T. Rauscher, N. Nishimura, R. Hirschi
Nucleosynthesis of heavy elements requires the use of different experimental and theoretical methods to determine astrophysical reaction rates than light element nucleosynthesis. A…
Carbon-rich presolar grains from massive stars. Subsolar 12C/13C and 14N/15N ratios and the mystery of 15N
M. Pignatari, E. Zinner, P. Hoppe +7
Carbon-rich grains with isotopic anomalies compared to the Sun are found in primitive meteorites. They were made by stars, and carry the original stellar nucleosynthesis signature.…
Production of 92Nb, 92Mo, and 146Sm in the gamma-process in SNIa
T. Rauscher, C. Travaglio, R. Gallino +2
The knowledge of the production of extinct radioactivities like 92Nb and 146Sm by photodisintegration processes in ccSN and SNIa models is essential for interpreting abundances in…
