discov_num notes refcode
STFA 55 B is BD+36@4537.
Toyota et al. (2009) monitored the RV of the A component every 1-2
months between 2003 Mar - 2007 Nov, using a high-dispersion echelle
(precision ~10 m/s). The star shows a large RV variation; a Keplerian
fit gives a period of 863.8d and an eccentricity of 0.20, which may be
induced by a companion of mass ~8.1 Mjup, by stellar rotation or by
non-radial pulsation. Toy2009
