Disc-binary interactions in depleted post-AGB binaries

Glenn-Michael Oomen, Onno Pols, Hans Van Winckel +1

Binary post-asymptotic giant branch (post-AGB) stars have orbital periods in the range of 100--2500 days in eccentric orbits. They are surrounded by circumbinary dusty discs. They…

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…

Orbital properties of binary post-AGB stars

Glenn-Michael Oomen, Hans Van Winckel, Onno Pols +5

Binary post-asymptotic giant branch (post-AGB) stars are thought to be the products of a strong but poorly-understood interaction during the AGB phase. The aim of this contribution…
