The molecular and dusty composition of Betelgeuse's inner circumstellar environment
Guy Perrin, Tijl Verhoelst, Stephen T. Ridgway +6
The study of the atmosphere of red supergiant stars in general and of Betelgeuse (alpha Orionis) in particular is of prime importance to understand dust formation and how mass is l…
ISO Mid-Infrared Spectroscopy of Galactic Bulge AGB Stars
Joris A. D. L. Blommaert, Martin A. T. Groenewegen, Koryo Okumura +8
To study the nature of Bulge AGB stars and in particular their circumstellar dust, we have analysed mid-infrared spectra obtained with the ISOCAM CVF spectrometer in three Bulge fi…
Spitzer Observations of Deeply Obscured Galactic Nuclei
H. W. W. Spoon, J. V. Keane, J. Cami +4
We report on our first results from a mid-infrared spectroscopic study of ISM features in a sample of deeply obscured ULIRG nuclei using the InfraRed Spectrograph (IRS) on the Spit…
The Rotational Excitation Temperature of the 6614 Diffuse Interstellar Band Carrier
J. Cami, F. Salama, J. Jiménez-Vicente +2
Analysis of high spectral resolution observations of the 6614 diffuse interstellar band (DIB) line profile show systematic variations in the positions of the peaks in the substr…
Mass loss and rotational CO emission from Asymptotic Giant Branch stars
F. Kemper, R. Stark, K. Justtanont +5
We present submillimeter observations of rotational transitions of carbon monoxide from J = 2 -> 1 up to 7 -> 6 for a sample of Asymptotic Giant Branch stars and red supergiants. I…
Simultaneous Optical and X-ray Observations of Flares and Rotational Modulation on the RS CVn Binary HR 1099 (V711 Tau) from the MUSICOS 1998 Campaign
D. Garcia-Alvarez, B. H. Foing, D. Montes +2
We present simultaneous and continuous observations of the H, H, He {\sc i} D, Na {\sc i} D,D doublet and the Ca {\sc ii} H & K lines for the RS CVn system…
