Remarks

22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 27 MJ and inclination of 16.1 deg
The object at 0.43 UA is interpreted by Mazeh et al. 1996 to be a brown dwarf, in view of its high eccentricity e = 0.4
Upper mass limit of 38 MJ given by Hipparcos (Perryman et al. 1996)
