We present astrometric and spectroscopic observations conÐrming that two nearby G dwarf systems (Gliese 417 \ BD]36¡2162 and Gliese 584AB \ g CrB AB) have a widely separated, L dwarf, substellar companion. Using age estimates of the G dwarf primaries, we estimate masses for these L dwarfs from theoretical evolutionary tracks. For the L4.5 dwarf Gl 417B we… CONTINUE READING
