19 Oct 2010: Simpson et al. (2010) infer the orbital inclination from the parent star rotation, deriving a planet mass 0.2+0.2-0MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
24 Aug. 2006: A brown dwarf companion (M = 20 to 60 MJup, projected separation 480 AU) has been detected by direct imaging (Luhman et al. 2006, Mugrauer et al 2006). The brown dwarf is added in the base as HD 3651 B.
