The chemical fingerprint of the Gaia BH3 system. Evidence for early cluster enrichment from the analysis of 51 elements
Gregory Vanden Broeck, Thibault Merle, Nhat Tan Mai +5
The Gaia BH3 system hosts the most massive known stellar-origin black hole and a low-mass metal-poor companion whose chemical composition may constrain early explosive nucleosynthe…
Stellar nucleosynthesis in the era of large surveys: S-process polluted binaries in GALAH DR4
A. Escorza, S. Vitali, D. Godoy-Rivera +11
Binary interactions during the AGB phase can lead to the formation of chemically peculiar stars with overabundances of s-process elements. Only a few hundreds of these stars have b…
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…
Technetium-rich M Stars: Prime diagnostics of recent third dredge-up events on the Asymptotic Giant Branch
Shreeya Shetye, Sophie Van Eck, Alain Jorissen +6
Context. Technetium (Tc)-rich M-type stars have been known for over 45 years. However, the origin of Tc in these stars, particularly its detection without the concomitant detection…
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…
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…
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…
Systematic study of the low-lying electric dipole strength in Sn isotopes and its astrophysical implications
M. Markova, A. C. Larsen, P. von Neumann-Cosel +8
The -ray strength functions (GSF) and nuclear level densities (NLD) below the neutron threshold have been extracted for Sn from particle- coincidence…
The intermediate neutron capture process: IV. Impact of nuclear model and parameter uncertainties
S. Martinet, A. Choplin, S. Goriely +1
We investigate both the systematic and statistical uncertainties associated with theoretical nuclear reaction rates of relevance during the i-process and explore their impact on th…
