SPITZER survey of dust grain processing in stable discs around binary post-AGB stars
C. Gielen, H. Van Winckel, M. Min +2
Aims: We investigate the mineralogy and dust processing in the circumbinary discs of binary post-AGB stars using high-resolution TIMMI2 and SPITZER infrared spectra. Methods: We pe…
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…
