Production of n-rich nuclei in red giant stars
Maurizio M. Busso, Sara Palmerini
We outline a partial historical summary of the steps through which the nucleosynthesis phenomena induced by {\it slow} neutron captures (the {\it s-process}) were clarified, a scie…
Oxygen and Aluminum-Magnesium Isotopic Systematics of Presolar Nanospinel Grains from CI Chondrite Orgueil
Nan Liu, Nicolas Dauphas, Sergio Cristallo +2
Presolar oxide grains have been previously divided into several groups (Group 1 to 4) based on their isotopic compositions, which can be tied to several stellar sources. Much of av…
New Multielement Isotopic Compositions of Presolar SiC Grains: Implications for Their Stellar Origins
Nan Liu, Jens Barosch, Larry R. Nittler +5
We report NanoSIMS Si and Mg-Al isotopic data (and C, N, and Ti isotopic data when available) for 85 submicron- to micron-sized presolar SiC grains from the CM2 Murchison meteorite…
Theoretical estimate of the half-life for the radioactive Cs and Cs in astrophysical scenarios
S. Taioli, D. Vescovi, M. Busso +4
We analyze the CsBa and CsBa decays, which are crucial production channels for Ba isotopes in Asympt…
Presolar grain isotopic ratios as constraints to nuclear and stellar parameters of AGB nucleosynthesis
Sara Palmerini, Maurizio Busso, Diego Vescovi +8
Recent models for evolved Low Mass Stars (with ), undergoing the AGB phase assume that magnetic flux-tube buoyancy drives the formation of C reservoirs…
Magnetic-buoyancy-induced mixing in AGB Stars: fluorine nucleosynthesis at different metallicities
D. Vescovi, S. Cristallo, S. Palmerini +2
Asymptotic giant branch (AGB) stars are considered to be among the most significant contributors to the fluorine budget in our Galaxy. While at close-to-solar metallicity observati…
