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…
A Search for Mid-Infrared Molecular Hydrogen Emission from Protoplanetary Disks
A. Carmona, M. E van den Ancker, Th. Henning +6
We observed the Herbig Ae/Be stars UX Ori, HD 34282, HD 100453, HD 101412, HD 104237 and HD 142666, and the T Tauri star HD 319139 and searched for H2 0-0 S(2) emission at 12.278 m…
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.…
The compact circumstellar material around OH 231.8+4.2
M. Matsuura, O. Chesneau, A. A. Zijlstra +7
We have observed the bipolar post-AGB candidate OH 231.8+4.2, using the mid-infrared interferometer MIDI and the infrared camera with the adaptive optics system NACO on the Very La…
Probing the mass-loss history of AGB and red supergiant stars from CO rotational line profiles I. Theoretical model -- Mass-loss history unravelled in VY CMa
L. Decin, S. Hony, A. de Koter +3
Context: Mass loss plays a dominant role in the evolution of low mass stars while they are on the Asymptotic Giant Branch (AGB). The gas and dust ejected during this phase are a ma…
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…
