Production of Lithium and Heavy Elements in AGB Stars Experiencing PIEs
A. Choplin, L. Siess, S. Goriely +1
Asymptotic giant branch (AGB) stars can experience proton ingestion events (PIEs), leading to a rich nucleosynthesis. During a PIE, the intermediate neutron capture process (i-proc…
Proton ingestion in asymptotic giant branch stars as a possible explanation for J-type stars and AB2 grains
A. Choplin, L. Siess, S. Goriely
J-type stars are a subclass of carbon stars that are generally Li-rich, not enriched in s-elements, and have low C/C ratios. They were suggested to be the manufacture…
Rapidly rotating Population III stellar models as a source of primary nitrogen
Sophie Tsiatsiou, Yves Sibony, Devesh Nandal +12
The first stars might have been fast rotators. This would have important consequences for their radiative, mechanical and chemical feedback. We discuss the impact of fast initial r…
Massive stars evolution with new C12+C12 nuclear reaction rate -- the core carbon-burning phase
T. Dumont, E. Monpribat, S. Courtin +7
Nuclear reactions drive the stellar evolution and contribute to the stellar and galactic chemicals abundances. New determinations of the nuclear reaction rates for key fusion react…
The intermediate neutron capture process. V. The i-process in AGB stars with overshoot
A. Choplin, L. Siess, S. Goriely +1
The intermediate neutron capture process (i-process) can develop during proton ingestion events (PIE), potentially during the early stages of low-mass low-metallicity asymptotic gi…
