Dust-grain processing in circumbinary discs around evolved binaries. The RV Tauri spectral twins RU Cen and AC Her
C. Gielen, H. Van Winckel, L. B. F. M. Waters +2
Context: We study the structure and evolution of circumstellar discs around evolved binaries and their impact on the evolution of the central system. Aims: To study in detail the b…
Stellar population synthesis of post-AGB stars: the s-process in MACHO47.2496.8
A. Bonacic Marinovic, M. Lugaro, M. Reyniers +1
The low-metallicity RV Tauri star MACHO47.2496.8, recently discovered in the Large Magellanic Cloud, is highly enriched in carbon and heavy elements produced by the slow neutron ca…
IRAS08281-4850 and IRAS14325-6428: two A-type post-AGB stars with s-process enrichment
M. Reyniers, G. C. Van de Steene, P. A. M. van Hoof +1
One of the puzzling findings in the study of the chemical evolution of (post-)AGB stars is why very similar stars (in terms of metallicity, spectral type, infrared properties, etc.…
The circumbinary disc around the J-type C-star IRAS 18006-3213
P. Deroo, H. Van Winckel, T. Verhoelst +3
In the generally accepted, but poorly documented model, silicate J-type C-stars are binary objects for which the silicate emission originates from a circumbinary or a circumcompani…
Post-AGB Binaries
Hans Van Winckel
The specific characteristic of the SED of serendipitously discovered post-AGB binaries, allowed us to launch a very extensive multi-wavelength study of evolved objects, selected on…
First detection of photospheric depletion in the LMC
M. Reyniers, H. Van Winckel
Recent photospheric abundance studies of galactic field RV Tauri stars show that depletion of refractory elements is rather common in these evolved objects. The process that create…
