MWC 297: a young high-mass star rotating at critical velocity
B. Acke, T. Verhoelst, M. E. van den Ancker +9
MWC 297 is a young massive nearby B[e] star. The central star has a large projected rotational velocity of 350 km/s. Despite the wealth of published observations, the nature of thi…
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…
Binary post-AGB stars and their Keplerian discs
Hans Van Winckel, Tom Lloyd Evans, Maarten Reyniers +2
In this contribution we give a progress report on our systematic study of a large sample of post-AGB stars. The sample stars were selected on the basis of their infrared colours an…
Amorphous alumina in the extended atmosphere of Alpha Orionis
T. Verhoelst, L. Decin, R. Van Malderen +7
In this paper we study the extended atmosphere of the late-type supergiant Alpha Orionis. Infrared spectroscopy of red supergiants reveals strong molecular bands, some of which do…
V453 Oph: a s-process enriched, but carbon-deficient RV Tauri star of low intrinsic metallicity
Pieter Deroo, Maarten Reyniers, Hans Van Winckel +2
This paper reports the detection of a heavy element enriched RV Tauri variable with an abundance pattern that differs significantly from a standard s-process enriched object: V453…
