Observations of the Goldreich-Kylafis effect in star-forming regions with XPOL at the IRAM 30m telescope
Jan Forbrich, Helmut Wiesemeyer, Clemens Thum +2
The Goldreich-Kylafis (GK) effect causes certain molecular line emission to be weakly linearly polarized, e.g., in the presence of a magnetic field. Compared to polarized dust emis…
A multi-wavelength study of a double intermediate-mass protostar - from large-scale structure to collimated jets
Jan Forbrich, Thomas Stanke, Randolf Klein +4
(abridged) We study a previously discovered protostellar source that is deeply embedded and drives an energetic molecular outflow. The source, UYSO1, is located close to IRAS 07029…
New M dwarf debris disk candidates in NGC 2547
Jan Forbrich, Charles J. Lada, August A. Muench +1
With only six known examples, M-dwarf debris disks are rare, even though M dwarfs constitute the majority of stars in the Galaxy. After finding a new M dwarf debris disk in a shall…
A 1.3 cm wavelength radio flare from a deeply embedded source in the Orion BN/KL region
Jan Forbrich, Karl M. Menten, Mark J. Reid
Aims: Our aim was to measure and characterize the short-wavelength radio emission from young stellar objects (YSOs) in the Orion Nebula Cluster and the BN/KL star-forming region. M…
Coronae in the Coronet: A very deep X-ray look into a stellar nursery
Jan Forbrich, Thomas Preibisch
In order to study the X-ray properties of young stellar objects (YSOs), we analyze an exceptionally sensitive Chandra dataset of the Coronet cluster in the CrA star-forming region,…
The distance to the Orion Nebula
K. M. Menten, M. J. Reid, J. Forbrich +1
We have used the Very Long Baseline Array to measure the trigonometric parallax of several member stars of the Orion Nebula Cluster showing non-thermal radio emission. We have dete…
