A coronagraphic search for wide sub-stellar companions among members of the Ursa Major moving group

M. Ammler-von Eiff, A. Bedalov, C. Kranhold +4

We present the results of a survey to detect low-mass companions of UMa group members, carried out in 2003-2006 with NACO at the ESO VLT. While many extra-solar planets and planeta…

New companions in the stellar systems of DI Cha, Sz 22, CHXR 32, and Cha Halpha 5 in the Cha I star-forming region

T. O. B. Schmidt, N. Vogt, R. Neuhäuser +2

The star-forming regions in Chamaeleon (Cha) are among the nearest (distance ~165 pc) and youngest (age ~2 Myrs) conglomerates of recently formed stars and among the ideal targets…

Astrometric confirmation of young low-mass binaries and multiple systems in the Chamaeleon star-forming regions

N. Vogt, T. O. B. Schmidt, R. Neuhäuser +4

The star-forming regions in Chamaeleon are one of the nearest (distance ~165 pc) and youngest (age ~2 Myrs) conglomerates of recently formed stars and the ideal target for populati…

New astrometry and photometry for the companion candidates of CT Cha

T. O. B. Schmidt, R. Neuhäuser, M. Mugrauer +2

In our ongoing search for close and faint companions around T Tauri stars in the Chamaeleon star-forming region, we recently (Schmidt et al 2008b) presented direct observations and…

A search for wide brown dwarf companions to stars within 10pc

Marin Treselj, Andreas Seifahrt, Klaus-Werner Hodapp +2

We present the first results of a large imaging survey to identify wide brown dwarf companions to stars within 10 pc. We have performed a deep (H-band limit ~ 19.0 mag), wide field…

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…
