Gas and dust from solar metallicity AGB stars
P. Ventura, A. Karakas, F. Dell'Agli +2
We study the asymptotic giant branch (AGB) evolution of stars with masses between . We focus on stars with a solar chemical composition, which allows u…
C/O ratios in planetary nebulae with dual-dust chemistry from faint optical recombination lines
J. García-Rojas, G. Delgado-Inglada, D. A. García-Hernández +4
We present deep high-resolution (R~15,000) and high-quality UVES optical spectrophotometry of nine planetary nebulae with dual-dust chemistry. We compute physical conditions from s…
Organic molecules, ions, and rare isotopologues in the remnant of the stellar-merger candidate, CK Vulpeculae (Nova 1670)
T. Kamiński, K. M. Menten, R. Tylenda +3
CK Vul is a star whose outburst was observed in 1670-72. A stellar-merger event was proposed to explain its ancient eruption. Aims: We aim to investigate the composition of the mol…
Overshoot Inwards from the Bottom of the Intershell Convective Zone in (S)AGB stars
J. C. Lattanzio, C. A. Tout, E. V. Neumerzhitckii +2
We estimate the extent of overshooting inwards from the bottom of the intershell convective zone in thermal pulses in (S)AGB stars. We find that the buoyancy is so strong that any…
Partial mixing and the formation of 13C pockets in AGB stars: effects on the s-process elements
J. F. Buntain, C. L. Doherty, M. Lugaro +3
The production of the elements heavier than iron via slow neutron captures (the s process) is a main feature of the contribution of asymptotic giant branch (AGB) stars of low mass…
Rubidium and zirconium abundances in massive Galactic asymptotic giant branch stars revisited
V. Perez-Mesa, O. Zamora, D. A. Garcia-Hernandez +4
Luminous Galactic OH/IR stars have been identified as massive (>4-5 M_s) AGB stars experiencing HBB and Li production. Their Rb abundances and [Rb/Zr] ratios derived from hydrostat…
