discov_num notes refcode
COU2031 1985.740: The separation of this partially resolved pair was
calculated under the assumption of zero or otherwise known magnitude
difference. Tok1985
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.53 +/- 0.35, 2.85, and 1.05 Msun, respectively. Mlk2012
Combined spectroscopic/interferometric orbit. Resulting masses are
1.75 +/- 0.08 and 1.32 +/- 0.08 Msun. Spectral types are estimated as
G3IV and F6V. Doc2014i
