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…
Fluorine and Sodium in C-rich low-metallicity stars
Sara Lucatello, Thomas Masseron, Jennifer A. Johnson +2
We present the N, O, F and Na abundance and 12C/13C isotopic ratio measurements or upper limits for a sample of 10 C-rich, metal-poor giant stars, eight enhanced in s-process (CEMP…
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…
