Modelling depletion by re-accretion of gas from a dusty disc in post-AGB stars
Glenn-Michael Oomen, Hans Van Winckel, Onno Pols +1
Many disc-type post-asymptotic giant branch (post-AGB) stars are chemically peculiar, showing underabundances of refractory elements in their photospheres that correlate with conde…
The spectroscopic binaries RV Tauri and DF Cygni
Rajeev Manick, Devika Kamath, Hans Van Winckel +7
Aim: The focus of this paper is on two famous but still poorly understood RV Tauri stars: RV Tau and DF Cyg. We aim at confirming their suspected binary nature and deriving their o…
Barium & related stars and their white-dwarf companions II. Main-sequence and subgiant stars
A. Escorza, D. Karinkuzhi, A. Jorissen +12
Barium (Ba) dwarfs and CH subgiants are the less-evolved analogues of Ba and CH giants. They are F- to G-type main-sequence stars polluted with heavy elements by a binary companion…
