CEMP-s and CEMP-s/r stars: last update
S. Bisterzo, R. Gallino, O. Straniero +3
We provide an updated discussion of the sample of CEMP-s and CEMP-s/r stars collected from the literature. Observations are compared with the theoretical nucleosynthesis models of…
AGB yields and Galactic Chemical Evolution: last updated
S. Bisterzo, C. Travaglio, M. Wiescher +7
We study the s-process abundances at the epoch of the Solar-system formation as the outcome of nucleosynthesis occurring in AGB stars of various masses and metallicities. The calcu…
The effects of rotation on the s-process nucleosynthesys in Asymptotic Giant Branch stars
L. Piersanti, S. Cristallo, O. Straniero
In this paper we analyze the effects induced by rotation on low mass Asymptotic Giant Branch stars. We compute two sets of models, M=2.0 Msun at [Fe/H]=0 and M=1.5 Msun at [Fe/H]=-…
Luminosities of Carbon-rich Asymptotic Giant Branch stars in the Milky Way
Roald Guandalini, Sergio Cristallo
Stars evolving along the Asymptotic Giant Branch can become Carbon-rich in the final part of their evolution. They replenish the inter-stellar medium with nuclear processed materia…
Nitrogen isotopes in AGB carbon stars and presolar SiC grains: a challenge for stellar nucleosynthesis
R. Hedrosa, C. Abia, M. Busso +5
Isotopic ratios of C, N, Si, and trace heavy elements in presolar SiC grains from meteorites provide crucial constraints to nucleosynthesis. A long-debated issue is the origin of t…
Europium s-process signature at close-to-solar metallicity in stardust SiC grains from AGB stars
Janaina N. Avila, Trevor R. Ireland, Maria Lugaro +5
Individual mainstream stardust silicon carbide (SiC) grains and a SiC-enriched bulk sample from the Murchison carbonaceous meteorite have been analyzed by the Sensitive High Resolu…
