Kelu-1 AB - A possible brown dwarf triple system
M. B. Stumpf, W. Brandner, Th. Henning +5
We have monitored the benchmark L dwarf binary Kelu-1AB over the past 3 years to derive improved spectral types and luminosities for the individual components. The astrometric meas…
Near-IR observations of UCHII regions
Carlos Alvarez, Markus Feldt, Thomas Henning +3
We present adaptive-optics (AO) assisted J, H and K/K' images of 8 UCHII regions taken with the ALFA and ADONIS AO systems at Calar Alto and La Silla observatories. The images show…
Infrared Imaging Polarimetry of Massive Star-forming Regions
Bringfried Stecklum, Thomas Henning, Markus Feldt +2
Imaging polarimetry is a useful tool to reveal the 3D structure of dust distributions and to localize embedded young stellar objects. We present maps of the linear polarization at…
High-resolution studies of massive star-forming regions
Thomas Henning, Markus Feldt, Bringfried Stecklum
We summarize the status of our program of near-infrared adaptive optics observations of ultracompact HII regions. By means of selected results we demonstrate the usefulness of this…
