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…
Impact of the Tayler magnetic instability on the surface abundance of boron in massive stars
L. Asatiani, P. Eggenberger, M. Marchand +3
Context: The surface abundances of massive stars show evidence of internal mixing, while asteroseismic data suggest that efficient angular momentum (AM) transport occurs in stellar…
