dc.descriptionWe present the results of a HST/NICMOS coronagraphic survey for the direct detection of substellar companions within the young TW Hydrae and Tucana Associations. At the distance of these associations, the lower mass limit of detection, based on models, is well into the high mass planet region for separations > 30 AU. Results presented here include spectra and proper motion verification of two brown dwarf companions, TWA 5B and HR 7329B, located 100 AU and 180 AU from their primaries, respectively. We also present a possible exo-solar giant planet candidate located 125 AU from TWA 6. These few examples demonstrate that the young associations remain fertile ground for discovery and environmental study of planetary systems.
