NuGrid stellar data set I. Stellar yields from H to Bi for stars with metallicities Z = 0.02 and Z = 0.01
M. Pignatari, F. Herwig, R. Hirschi +16
We provide a set of stellar evolution and nucleosynthesis calculations that applies established physics assumptions simultaneously to low- and intermediate-mass and massive star mo…
The 12C + 12C reaction and the impact on nucleosynthesis in massive stars
M. Pignatari, R. Hirschi, M. Wiescher +7
Despite much effort in the past decades, the C-burning reaction rate is uncertain by several orders of magnitude, and the relative strength between the different channels 12C(12C,a…
The effect of 12C + 12C rate uncertainties on the evolution and nucleosynthesis of massive stars
M. E. Bennett, R. Hirschi, M. Pignatari +8
[Shortened] The 12C + 12C fusion reaction has been the subject of considerable experimental efforts to constrain uncertainties at temperatures relevant for stellar nucleosynthesis.…
The effect of 12C + 12C rate uncertainties on the weak s-process component
Michael E. Bennett, Raphael Hirschi, Marco Pignatari +9
The contribution by massive stars (M > 9 solar masses) to the weak s-process component of the solar system abundances is primarily due to the 22Ne neutron source, which is activate…
The effect of 12C + 12C rate uncertainties on s-process yields
M E Bennett, R Hirschi, M Pignatari +9
The slow neutron capture process in massive stars (the weak s-process) produces most of the s-only isotopes in the mass region 60 < A < 90. The nuclear reaction rates used in simul…
Convective-reactive proton-C12 combustion in Sakurai's object (V4334 Sagittarii) and implications for the evolution and yields from the first generations of stars
Falk Herwig, Marco Pignatari, Paul R. Woodward +5
Depending on mass and metallicity as well as evolutionary phase, stars occasionally experience convective-reactive nucleosynthesis episodes. We specifically investigate the situati…
