Direct measurement of the size and shape of the present-day stellar wind of Eta Carinae

R. van Boekel, P. Kervella, M. Schoeller +7

We present new high angular resolution observations at near-IR wavelengths of the core of the Luminous Blue Variable Eta Carinae, using NAOS-CONICA at the VLT and VINCI at the VLT…

The peculiar circumstellar environment of NGC2024-IRS2

A. Lenorzer, A. Bik, A. de Koter +5

We re-examine the nature of NGC2024-IRS2 in light of the recent discovery of the late O-type star, IRS2b, located 5 arcsec from IRS2. Using L-band spectroscopy, we set a lower limi…

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…

The circumstellar envelope of the C-rich post-AGB star HD 56126

S. Hony, A. G. G. M. Tielens, L. B. F. M. Waters +1

We present a detailed study of the circumstellar envelope of the post-asymptotic giant branch ``21 micron object'' HD 56126. We build a detailed dust radiative transfer model of th…

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…
