υ And c Notes:
21 Aug 2012: The given mass is the minimum mass from Ligi et a; (2012). Benedict et al. (2010) give an orbital inclination of 8 deg., which would lead to a mass of 13.25 MJup.
19 Oct 2010: Simpson et al. (2010) infer the orbital inclination 58 deg. from the parent star rotation, deriving a planet mass 2.3+0.5-0.3MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
08 May 10: The value of the parameters are using dynamical stability analysis of the system (Table 15, McArthur et al 2010)
08 May 10: Mutual inclination between planets c and d: 30.4 deg.
20 Apr 03: Planet in wide (a ~ 750 AU) binary system (Eggenberger et al 2003)
21 May 02:A M4.5 V stellar companion detected at ~ 750 AU (Lowrance et al. 2002)
22 Nov 00: From astrometry Han et al. (2000) claim a preliminary mass of 10 MJ and inclination of 155.5o for the planet d.
Circumstellar disk searched for at UKIRT and KECK but not found (Trilling et al.1999, 2000)
