Presolar Silicon Carbide Grains of Types Y and Z: Their Strontium and Barium Isotopic Compositions and Stellar Origins
Nan Liu, Thomas Stephan, Sergio Cristallo +5
We report the Sr and Ba isotopic compositions of 18 presolar SiC grains of types Y (11) and Z (7), rare types commonly argued to have formed in lower-than-solar metallicity asympto…
The CERN n TOF NEAR station for astrophysics- and application-related neutron activation measurements
N. Patronis, A. Mengoni, N. Colonna +130
A new experimental area, the NEAR station, has recently been built at the CERN n TOF facility, at a short distance from the spallation target (1.5 m). The new area, characterized b…
Direct measurement of the 13C(α,n)16O cross section into the s-process Gamow peak
G. F. Ciani, L. Csedreki, D. Rapagnani +45
One of the main neutron sources for the astrophysical s-process is the reaction 13C(α,n)16O, taking place in thermally pulsing Asymptotic Giant Branch stars at temperatures around…
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…
Magnetic-buoyancy-induced mixing in AGB Stars: a theoretical explanation of the non-universal [Y/Mg]-age relation
Magrini L., Vescovi D., Casali G. +6
The use of abundance ratios involving Y, or other slow-neutron capture elements, are routinely used to infer stellar ages.Aims.We aim to explain the observed [Y/H] and [Y/Mg] abund…
