Probing the Early Evolution of Young High-Mass Stars
E. Puga, A. Bik, L. B. M. F. Waters +22
Near-infrared imaging surveys of high-mass star-forming regions reveal an amazingly complex interplay between star formation and the environment (Churchwell et al. 2006; Alvarez et…
Three-micron spectra of AGB stars and supergiants in nearby galaxies
M. Matsuura, A. A. Zijlstra, J. Th. van Loon +7
The dependence of stellar molecular bands on the metallicity is studied using infrared L-band spectra of AGB stars (both carbon-rich and oxygen-rich) and M-type supergiants in the…
The Mid-IR spatially resolved environment of OH26.5+0.6 at maximum luminosity
O. Chesneau, T. Verhoelst, B. Lopez +6
We present observations of the famous OH/IR star OH26.5+0.6 obtained using the Mid-Infrared Interferometric Instrument MIDI at the European Southern Observatory (ESO) Very Large Te…
The mineralogy, geometry and mass-loss history of IRAS 16342-3814
C. Dijkstra, L. B. F. M. Waters, F. Kemper +5
We present the 2-200 um Infrared Space Observatory (ISO) spectrum and 3.8-20 um ISAAC and TIMMI2 images of the extreme OH/IR star IRAS 16342-3814. Amorphous silicate absorption fea…
Understanding the spectra of isolated Herbig stars in the frame of a passive disk model
C. Dominik, C. P. Dullemond, L. B. F. M. Waters +1
We discuss spectral energy distributions of a sample of Herbig Ae/Be stars in the context of a passive irradiated disk model. The data have been presented earlier by Meeus et al (2…
