Submillimetre continuum emission from Class 0 sources: Theory, Observations, and Modelling
Miriam Rengel, Klaus Hodapp, Dirk Froebrich +2
We report on a study of the thermal dust emission of the circumstellar envelopes of a sample of Class 0 sources. The physical structure (geometry, radial intensity profile, spatial…
Modelling of the continuum emission from Class 0 sources
M. Rengel, D. Froebrich, S. Wolf +1
Class 0 sources are objects representing the earliest phase of the protostellar evolution. Since they are highly obscured by an extended dusty envelope, these objects emit mainly i…
Pre-main sequence binaries with aligned disks ?
Sebastian Wolf, Bringfried Stecklum, Thomas Henning
We present the results of a study performed with the goal to investigate whether low-mass pre-main sequence binary stars are formed by multiple fragmentation or via stellar capture…
Detailed optical studies of the galactic supersoft X-ray source QR And (RXJ0019.8+2156)
B. Deufel, H. Barwig, D. Simic +2
We present high-speed long term photometric observations from 1992 to 1996 (UBVRI), as well as recently obtained (1997) spectrophotometric and high resolution spectroscopic studies…
