υ And d Notes:
19 Oct 2010: Simpson et al. (2010) infer the orbital inclination 58 deg. from the parent star rotation, deriving a planet mass 4.7+0.8-0.8MJ; 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)

Star

Alias HD 9826

08 May 2010: RV measurements also reveal a long-period trend indicating a fourth planet in the system (McArthur et al. 2010)
