Evolution of dust and ice features around FU Orionis objects
S. P. Quanz, Th. Henning, J. Bouwman +5
(abridged) We present spectroscopy data for a sample of 14 FUors and 2 TTauri stars observed with the Spitzer Space Telescope or with the Infrared Space Observatory (ISO). Based on…
A Hubble View of Star Forming Regions in the Magellanic Clouds
D. A. Gouliermis, Th. Henning, W. Brandner +13
The Magellanic Clouds (MCs) offer an outstanding variety of young stellar associations, in which large samples of low-mass stars (with masses less than 1 solar mass) currently in t…
Clustered Star Formation in the Small Magellanic Cloud. A Spitzer/IRAC View of the Star-Forming Region NGC 602/N 90
Dimitrios A. Gouliermis, Sascha P. Quanz, Thomas Henning
We present Spitzer/IRAC photometry on the star-forming HII region N 90, related to the young stellar association NGC 602 in the Small Magellanic Cloud. Our photometry revealed brig…
Deeply embedded objects and shocked molecular hydrogen: The environment of the FU Orionis stars RNO 1B/1C
S. P. Quanz, Th. Henning, J. Bouwman +2
We present Spitzer IRAC and IRS observations of the dark cloud L1287. The mid-infrared (MIR) IRAC images show deeply embedded infrared sources in the vicinity of the FU Orionis obj…
Dust rings and filaments around the isolated young star V1331 Cygni
Sascha P. Quanz, Daniel Apai, Thomas Henning
We characterize the small and large scale environment of the young star V1331 Cygni with high resolution HST/WFPC2 and Digitized Sky Survey images. In addition to a previously know…
Disks around young stars with VLTI/MIDI
Roy van Boekel, Peter Abraham, Serge Correia +17
We report on observations of circumstellar disks around young stars that have been obtained with the MIDI instrument, which is mounted on the VLT Interferometer and operates in the…
