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…

The 13C-Pocket Structure in AGB Models: Constraints from Zirconium Isotope Abundances in Single Mainstream SiC Grains

Nan Liu, Roberto Gallino, Sara Bisterzo +3

We present postprocess AGB nucleosynthesis models with different C-pocket internal structures to better explain zirconium isotope measurements in mainstream presolar SiC gra…

Barium Isotopic Composition of Mainstream Silicon Carbides from Murchison: Constraints for s-Process Nucleosynthesis in AGB Stars

Nan Liu, Michael R. Savina, Andrew M. Davis +10

We present barium, carbon, and silicon isotopic compositions of 38 acid-cleaned presolar SiC grains from Murchison. Comparison with previous data shows that acid washing is highly…

The impact of updated Zr neutron-capture cross sections and new asymptotic giant branch models on our understanding of the s process and the origin of stardust

Maria Lugaro, Giuseppe Tagliente, Amanda I. Karakas +4

We present model predictions for the Zr isotopic ratios produced by slow neutron captures in C-rich asymptotic giant branch (AGB) stars of masses 1.25 to 4 Msun and metallicities Z…
