discov_num notes refcode
STF1962 178 Lib. A is a spectroscopic binary. B is BD-08@4031.
HIP 76603. B = HIP 76602. Tok2011a
H N 33. MEv2010
Toyota et al. (2009) monitored the RV of both the A and B components
every 1-2 months between 2003 Mar - 2007 Nov, using a high-dispersion
echelle (precision ~10 m/s). The A component is a known SB1 (Tokovinin
& Gornya 2001; P=844.74d). Toyota et al. derive orbital elements in Tok2001
reasonable agreement with the earlier solution. The standard deviation
of radial velocities for the B component <40 m/s and velocities show
no periodic variation. This result rejects the association of a planet
of mass > 1.8 Mjup with this star. Toy2009
