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…
The infrared emission spectra of compositionally inhomogeneous aggregates composed of irregularly shaped constituents
M. Min, J. W. Hovenier, L. B. F. M. Waters +1
In order to deduce properties of dust in astrophysical environments where dust growth through aggregation is important, knowledge of the way aggregated particles interact with radi…
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…
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…
The shape and composition of interstellar silicate grains
M. Min, L. B. F. M. Waters, A. de Koter +3
We investigate the composition and shape distribution of silicate dust grains in the interstellar medium. The effect of the amount of magnesium in the silicate lattice is studied.…
Disks around young stars with VLTI/MIDI
Roy van Boekel, Peter Abraham, Serge Correia +17
We report on observations of circumstellar disks around young stars that have been obtained with the MIDI instrument, which is mounted on the VLT Interferometer and operates in the…
