  We report first results from our ground-based infrared imaging search for
sub-stellar companions (brown dwarfs and giant planets) of young (up to 100
Myrs) nearby (up to 100 pc) stars, where companions should be well separated
from the central stars and still relatively bright due to ongoing accretion
and/or contraction. Our observations are performed mainly with SOFI and SHARP
at the ESO 3.5m NTT on La Silla (imaging) and with ISAAC at the ESO 8.2m Antu
(VLT-UT1) on Cerro Paranal (imaging and spectroscopy), all in the H- and
K-bands. Here, we present new companion candidates around three T Tauri stars
(TWA-8 A, RXJ1121.1-3845, and RXJ1121.3-3447 N) in the TW Hya group, which
would have been sub-stellar if at the same distance and age as the T Tauri
stars, but are found to be background stars by spectroscopy.
