New constraints on the major neutron source in low-mass AGB stars
Nan Liu, Roberto Gallino, Sergio Cristallo +4
We compare updated Torino postprocessing asymptotic giant branch (AGB) nucleosynthesis model calculations with isotopic compositions of mainstream SiC dust grains from low-mass AGB…
Observing the metal-poor solar neighbourhood: a comparison of galactic chemical evolution predictions
T. Mishenina, M. Pignatari, B. Cot'e +14
Atmospheric parameters and chemical compositions for ten stars with metallicities in the region of -2.2< [Fe/H] <-0.6 were precisely determined using high resolution, high signal t…
Galactic Chemical Evolution: the Impact of the 13C-pocket Structure on the s-process Distribution
S. Bisterzo, C. Travaglio, M. Wiescher +2
The solar s-process abundances have been analyzed in the framework of a Galactic Chemical Evolution (GCE) model. The aim of this work is to implement the study by Bisterzo et al. (…
The Branchings of the Main s-process: Their Sensitivity to alpha-induced Reactions on 13C and 22Ne and to the Uncertainties of the Nuclear Network
Sara Bisterzo, Roberto Gallino, Franz Kaeppeler +6
This paper provides a detailed analysis of the main component of the slow neutron capture process (the s-process), which accounts for the solar abundances of half of the nuclei wit…
The -pockets in AGB Stars and Their Fingerprints in Mainstream SiC Grains
Nan Liu, Andrew M. Davis, Roberto Gallino +5
We identify three isotopic tracers that can be used to constrain the -pocket and show the correlated isotopic ratios of Sr and Ba in single mainstream presolar SiC grains.…
Correlated Strontium and Barium Isotopic Compositions of Acid-Cleaned Single Silicon Carbides from Murchison
Nan Liu, Michael R. Savina, Roberto Gallino +8
We present strontium, barium, carbon, and silicon isotopic compositions of 61 acid-cleaned presolar SiC grains from Murchison. Comparison with previous data shows that acid washing…
