Gas and dust from metal-rich AGB stars
Paolo Ventura, Flavia Dell'Agli, Maria Lugaro +3
Context: Stars evolving through the asymptotic giant branch (AGB) phase provide significant feedback to their host system, in form of both gas enriched in nuclear-burning products…
129I and 247Cm in Meteorites Constrain the Last Astrophysical Source of Solar r-process Elements
Benoit Côté, Marius Eichler, Andrés Yagüe +12
The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron-capture process (r process), but the ast…
Galactic planetary nebulae with precise nebular abundances as a tool to understand the evolution of asymptotic giant branch stars
D. A. Garcia-Hernandez, P. Ventura, G. Delgado-Inglada +3
We present nucleosynthesis predictions (HeCNOCl) from asymptotic giant branch (AGB) models, with diffusive overshooting from all the convective borders, in the metallicity range Z/…
Hot bottom burning and s-process nucleosynthesis in massive AGB stars at the beginning of the thermally-pulsing phase
D. A. Garcia-Hernandez, O. Zamora, A. Yagüe +5
We report the first spectroscopic identification of massive Galactic asymptotic giant branch (AGB) stars at the beginning of the thermal pulse (TP) phase. These stars are the most…
