Near-IR spectroscopy of OH/IR stars in the Galactic Centre
E. Vanhollebeke, J. A. D. L. Blommaert, M. Schultheis +2
Context. Galactic Centre (GC) OH/IR stars can be, based on the expansion velocities of their circumstellar shells, divided into two groups which are kinematically different and the…
A Spitzer mid-infrared spectral survey of mass-losing carbon stars in the Large Magellanic Cloud
Albert A. Zijlstra, Mikako Matsuura, Peter R. Wood +13
We present a Spitzer Space Telescope spectroscopic survey of mass-losing carbon stars (and one oxygen-rich star) in the Large Magellanic Cloud. The spectra cover the wavelength ran…
ESO-VLT and Spitzer spectroscopy of IRAS05328-6827: a massive young stellar object in the Large Magellanic Cloud

We present the first thermal-infrared spectra of an extra-galactic Young Stellar Object (YSO), IRAS05328-6827 in the HII region LHA 120-N148 in the Large Magellanic Cloud. The obse…
Mira Variables in the OGLE Bulge fields
M. A. T. Groenewegen, J. A. D. L. Blommaert
(abridged) The 222000 I-band light curves of variable stars detected by the OGLE-II survey in the direction of the Galactic Bulge have been fitted and have also been correlated wit…
65 Cybele in the thermal infrared: Multiple observations and thermophysical analysis
T. G. Müller, J. A. D. L. Blommaert
We investigated the physical and thermal properties of 65 Cybele}, one of the largest main-belt asteroids. Based on published and recently obtained thermal infrared observations, i…
ISOGAL: A deep survey of the obscured inner Milky Way with ISO at 7 and 15 micron and with DENIS in the near-infrared
A. Omont, G. Gilmore, C. Alard +38
The ISOGAL project is an infrared survey of specific regions sampling the Galactic Plane selected to provide information on Galactic structure,stellar populations,stellar mass-loss…
