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…
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…
On the impact of the carbon fusion rate over the properties of superbursts -- Numerical simulations of superbursts with MESA
Martin Nava-Callejas, Stéphane Goriely, Nicolas Chamel
Context: Superbursts are very energetic explosions in the crust of neutron stars in Low-Mass X-ray Binaries (LMXBs). These are triggered by unstable carbon burning at $T\leq 10^{9}…
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 properties indicating the presence of hyperons in neutron stars
Andreas Bauswein, Aristeidis Nikolaidis, Georgios Lioutas +7
We describe distinctive stellar features indicating the presence of hyperons in neutron stars as compared to purely nucleonic systems. A strongly negative curvature of the mass-rad…
