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…
The age dependence of the Vega phenomenon: Observations
G. Decin, C. Dominik, L. B. F. M. Waters +1
We study the time dependency of Vega-like excesses using infrared studies obtained with the imaging photopolarimeter ISOPHOT on board of ISO. We review the different studies publis…
First Detection of Millimeter Dust Emission from Brown Dwarf Disks
R. Klein, D. Apai, I. Pascucci +2
We report results from the first deep millimeter continuum survey targeting Brown Dwarfs (BDs). The survey led to the first detection of cold dust in the disks around two young BDs…
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…
