discov_num notes refcode
BNU 3 Aa,Ab: 62 UMa. B is BD+32@2178.
This system is known to have a variable radial velocity. Bnu1986
Aa,Ab: Orbit determined by fitting revised Hipparcos intermediate
astrometric data. Derived component masses are 1.31 +/- 0.16 and
1.22 +/- 0.14 Msun. Ren2010
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.56 +/- 0.30, 2.91, and 1.25 Msun, respectively. Mlk2012
STT 575 AB: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
