NHR 9 = Gam Cep = Errai.
Neuhauser et al. (2007)resolved the wide pair of the gam Cep triple
system using the Subaru AO system. Their combined solution yielded
masses for Aa and B of 1.40 +/- 0.12 and 0.409 +/- 0.018 Msun, plus a
mass function for the planetary companion (M_Ab sin i) of 1.60 +/-
0.13 Mjup. Physical separation for the AB pair is 20.18 +/- 0.66 au. Nhr2007
