The s Process and Beyond
Maria Lugaro, Marco Pignatari, René Reifarth +1
Neutron captures produce the vast majority of abundances of elements heavier than iron in the Universe. Beyond the classical slow (s) and rapid (r) processes, there is observationa…
Galactic Chemical Evolution and solar s-process abundances: dependence on the 13C-pocket structure
S. Bisterzo, C. Travaglio, R. Gallino +2
We study the s-process abundances (A > 90) at the epoch of the solar-system formation. AGB yields are computed with an updated neutron capture network and updated initial solar abu…
Production of carbon-rich presolar grains from massive stars
M. Pignatari, M. Wiescher, F. X. Timmes +6
About a year after core collapse supernova, dust starts to condense in the ejecta. In meteorites, a fraction of C-rich presolar grains (e.g., silicon carbide (SiC) grains of Type-X…
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.…
