We have used the F160W filter ( 1.4 - 1.8 \mu m ) and the coronagraph on the Near-InfraRed Camera and Multi-Object Spectrometer ( NICMOS ) on the Hubble Space Telescope ( HST ) to survey 45 single stars with a median age of 0.15 Gyr , an average distance of 30 pc , and an average H-magnitude of 7 mag .
For the median age we were capable of detecting a 30 M _ { Jupiter } companion at separations between 15 and 200 AU .
A 5 M _ { Jupiter } object could have been detected at 30 AU around 36 % of our primaries .
For several of our targets that were less than 30 Myr old , the lower mass limit was as low as a Jupiter mass , well into the high mass planet region .
Results of the entire survey include the proper motion verification of five low-mass stellar companions , two brown dwarfs ( HR7329B and TWA5B ) and one possible brown dwarf binary ( Gl 577B/C ) .
