The impact of nuclear uncertainties on the p-process nucleosynthesis in Supernovae
S. Martinet, S. Goriely, A. Choplin
The p-process is responsible for the production of the stable neutron-deficient nuclei heavier than iron observed in the solar system. However, important nuclear uncertainties stil…
Detection of actinides in CEMP-rs stars
A. M. Riyas, D. Karinkuzhi, S. Van Eck +4
The carbon-enhanced metal-poor stars with hybrid enrichments of slow- and rapid neutron-capture elements, the so-called CEMP-rs stars, still raise many questions due to their elusi…
Probing the first generations of massive stars through fluorine in CEMP-no stars
Arthur Choplin, Georges Meynet
We investigate whether the first discovered fluorine-rich CEMP-no star, CS 29498043, can be explained by a very metal-poor rotating massive star. We consider single rotating ste…
The intermediate neutron capture process. VI. Proton ingestion and i-process in rotating magnetic asymptotic giant branch stars
A. Choplin, L. Siess, S. Goriely +2
The intermediate neutron-capture process (i-process) can occur during proton ingestion events (PIEs), which may take place in the early evolutionary phases of asymptotic giant bran…
Abundance of heavy r-process elements in CEMP-rs stars: The role of the i-process
A. M. Riyas, D. Karinkuzhi, S. Van Eck +6
Carbon-enhanced metal-poor (CEMP) stars are ancient stars enriched in carbon and heavy elements. Some of these stars exhibit enhanced s-process and/or r-process elements, hence are…
Statistical framework for nuclear parameter uncertainties in nucleosynthesis modeling of r- and i-process
S. Martinet, G. Goriely, A. Choplin +1
Propagating nuclear uncertainties to nucleosynthesis simulations is key to understand the impact of theoretical uncertainties on the predictions, especially for processes far from…
