Remarks

19 Oct 2010: Simpson et al. (2010) infer the orbital inclination from the parent star rotation, deriving a planet mass 28-19MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 54 MJ and inclination of 176.0o
24 July: The Geneva group finds different parameters for HD 92788 b (to be announced at the IAU General Assembly).
31 July: Fischer et al. revise the planet b parameters after new RV data.
