Edge-on disk around the T Tauri star [MR81] Halpha 17 NE in CrA
R. Neuhaeuser, S. Kraemer, M. Mugrauer +6
Using the speckle camera SHARP at the 3.5m ESO NTT, Köhler and collaborators found an object ~3.5 mag fainter in K only 1.3" north-east of the T Tauri star [MR81] Ha 17 in the Coro…
Direct evidence of a sub-stellar companion around CT Cha
T. O. B. Schmidt, R. Neuhäuser, A. Seifahrt +5
In our ongoing search for close and faint companions around T Tauri stars, we found a very faint (Ks=14.9mag, Ks_0=14.4mag) object, just ~2.67" northwest of the Chamaeleon star-for…
Confirmation of the binary status of Cha Halpha 2 - a very young low-mass binary in Chamaeleon
T. O. B. Schmidt, R. Neuhäuser, N. Vogt +3
Neuhaeuser & Comeron (1998, 1999) presented direct imaging evidence, as well as first spectra, of several young stellar and sub-stellar M6- to M8-type objects in the Cha I dark clo…
Astrometric and photometric monitoring of GQ Lup and its sub-stellar companion
Ralph Neuhaeuser, Markus Mugrauer, Andreas Seifahrt +2
Neuhaeuser et al. (2005) presented direct imaging evidence for a sub-stellar companion to the young T Tauri star GQ Lup. Common proper motion was highly significant, but no orbital…
2.3 micron CO emission and absorption from young high-mass stars in M17
V. H. Hoffmeister, R. Chini, C. M. Scheyda +3
We are studying the extremely young cluster of M17 to investigate the birth of high-mass stars and the initial mass function. Deep JHKL imaging and K-band spectroscopy from the VLT…
