Multiwavelength interferometric observations and modeling of circumstellar disks
A. A. Schegerer, T. Ratzka, P. A. Schuller +3
We investigate the structure of the innermost region of three circumstellar disks around pre-main sequence stars HD 142666, AS 205 N, and AS 205 S. We determine the inner radii of…
Dynamics during outburst: VLTI observations of the young eruptive star V1647 Ori during its 2003-2006 outburst
L. Mosoni, N. Sipos, P. Abraham +11
Context: It is hypothesized that low-mass young stellar objects undergo eruptive phases during their early evolution. The outburst of V1647 Ori between 2003 and 2006 offered a rare…
Spatially resolved detection of crystallized water ice in a TTauri object
Alexander A. Schegerer, Sebastian Wolf
We search for frozen water and its processing around young stellar objects (YSOs of class I/II). We try to detect potential, regional differences in water ice evolution within YSOs…
Spatially resolved mid-infrared observations of the triple system T Tauri
Th. Ratzka, A. A. Schegerer, Ch. Leinert +6
To enhance our knowledge of the characteristics and distribution of the circumstellar dust associated with the individual components of the young hierarchical triple system T Tau,…
Tracing the potential planet-forming regions around seven pre-main-sequence stars
A. A. Schegerer, S. Wolf, C. A. Hummel +2
We investigate the nature of the innermost regions of seven circumstellar disks around pre-main-sequence stars. Our object sample contains disks apparently at various stages of the…
Submillimeter Structure of the Disk of the Butterfly Star
S. Wolf, A. Schegerer, H. Beuther +2
We present a spatially resolved 894 micron map of the circumstellar disk of the Butterfly star in Taurus (IRAS 04302+2247), obtained with the Submillimeter Array (SMA). The predict…
