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…
The advanced evolution of massive stars: I. New reaction rates for carbon and oxygen nuclear reactions
T. Dumont, A. Bonhomme, A. Griffiths +9
The nuclear rates for reactions involving 12C and 16O are key to compute the energy release and nucleosynthesis of massive stars during their evolution. These rates shape the stell…
Synthesis of actinides and short-lived radionuclides during i-process nucleosynthesis in AGB stars
Arthur Choplin, Stephane Goriely, Lionel Siess +1
A complex interplay between mixing and nucleosynthesis is at work in asymptotic giant branch (AGB) stars. In addition to the slow neutron capture process (s-process), the intermedi…
Fluorine production in He-burning regions of massive stars during cosmic history
Sophie Tsiatsiou, Georges Meynet, Eoin Farrell +11
The origin of fluorine is still a debated question. AGB stars synthesise this element and likely contribute significantly to its synthesis in the present-day Universe. However, it…
