From the mailing list:
Planet mass: 6.4 M_Jup
Semi-major axis: 0.36 AU
Period: 271.6 d
The eccentricity seems to be unconstrained. The star is also known as Van Biesbroeck's Star, GJ 752B, Wolf 1055B and V1298 Aql, NLTT 47621, Zkh 289, BD+04 4048B, LFT 1467, 8pc 170.26B, [B2006] J191657.6+050902, CSI+04 4048 2, LHS 474, UBV 16317, [GKL99] 370, CSV 102917, LSPM J1916+0509, USNO-B1.0 0951-00432259, [RHG95] 3038, GEN# +1.00180617B, LTT 15646, USNO 885, G 22-22B, and 2MASS J19165762+0509021.
Curiously a claim was made for a planet in 1983, but this was not confirmed. |
