  Brown dwarfs occupy the important region in the mass range between stars and
planets. Their existence, ambigious until only recently, and their properties
give insight into stellar and planetary formation. We present statistical
results of an infrared, coronagraphic survey of young, nearby stars that
includes probable companions to three young G-type stars, Gl 503.2 (G2V), HD
102982 (G3V), and Gl 577 (G5V). The companion to Gl 577 is a possible binary
brown dwarf, according to evolution ary models. A dynamical determination of
the components' masses will be achievable in the near future and be an
excellent test of the predictive ability of the evolutionary models.
