Rubidium, zirconium, and lithium production in massive AGB stars
D. Yong Research School of Astronomy and Astrophysics, Mt. Stromlo Observatory, Cotter Rd., Weston, ACT Australia A recent survey of a large sample of massive Galactic asymptotic giant branch (AGB) stars shows that significant overabundances of rubidium (up to 100 times solar) are present in these stars. Zirconium, on the other hand, is not enriched compared to the solar abundance. These observ...
متن کاملThe s-process in rotating AGB stars
We discuss the occurrence of the s-process during the radiative interpulse phase of rotating AGB stars. Due to differential rotation, protons are mixed into C-rich layers after thermal pulses, in the course of the so called third dredge up episode. We follow the time evolution of key isotope abundances in the relevant layers with a post-processing code which includes time dependant mixing and n...
متن کاملMixing and the s-process in rotating AGB stars
We model the nucleosynthesis during a radiative interpulse phase of a rotating 3M⊙ Asymptotic Giant Branch (AGB) star. We find an enhanced production of the neutron source species C compared to non-rotating models due to shear mixing of protons and C at the core-envelope interface. We estimate that the resulting total production of heavy elements by slow neutron capture (s-process) is too low t...

متن کاملGalactic C and S Stars as Guidelines for Magellanic Cloud AGB Stars
The study of the evolutionary properties of Asymptotic Giant Branch stars still presents unresolved topics. Progress in the theoretical understanding of their evolution is hampered by the difficulty to empirically explain key physical parameters like their luminosity, mass loss rate and chemical abundances. We are performing an analysis of Galactic AGB stars trying to find constraints for these...
