19 Oct 2010: Simpson et al. (2010) infer the orbital inclination from the parent star rotation, deriving a planet mass 11+4-3MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
19 Apr. 04: Astrometric confirmation of a wide low-mass companion (Mugrauer et al 2004)
22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 97 MJ and inclination of 175.8o
