Context. This paper is part of a larger project in which we systematically study the chemical
abundances of Galactic and extragalactic post-asymptotic giant branch (post-AGB) stars …

Context. Our understanding of the s-process nucleosynthesis in asymptotic giant branch
(AGB) stars is incomplete. AGB models predict, for example, large overabundances of lead …

Context. This paper is part of a larger project in which we systematically study the chemical
abundances of extra-galactic post-asymptotic giant branch (post-AGB) stars. The aim of our …

Context. The photospheric abundances of evolved solar-type stars of different metallicities
serve as probes into stellar evolution theory. Aims. Stellar photospheres of post-asymptotic …

Context. This paper is part of a larger project in which we want to focus on the still poorly
understood asymptotic giant branch (AGB) third dredge-up processes and associated s …

Context. Barium (Ba) stars are polluted by material enriched in the slow neutron capture (s-
process) elements synthesised in the interior of their former asymptotic giant branch (AGB) …

Aims. We explore modifications to the current scenario for the slow neutron-capture process
(the s-process) in asymptotic giant branch (AGB) stars to account for the Pb deficiency …

We have derived elemental abundances for a sample of nine IRAS sources with colours
similar to those of post-asymptotic giant branch (post-AGB) stars. For IRAS 01259+ 6823 …

Context. The low-metallicity RV Tauri star MACHO 47.2496. 8, recently discovered in the
Large Magellanic Cloud, is highly enriched in carbon and heavy elements produced by the …

Context. Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron
produced by the slow neutron-capture process (s process). These stars belong to binary …
