discov_num notes refcode
COU 79 21 Ari. Couteau & Morel (1982) computed masses disagree with spectral Cou1982d
type. Authors suggest 3rd component (mass ~1 Msun) as possible
explanation. 1985.8375: This measure was erroneously attributed to
02130+0851 = MCA 5 by McAlister et al. (1987). The data were re-reduced McA1987b
by Hartkopf et al., giving similar results. The measure has now been Hrt1996a
replaced by the mean of the two separate reduction results.
1986.567: The separation of this partially resolved pair was
calculated under the assumption of zero or otherwise known magnitude
difference. Pair passed periastron earlier than predicted; now the
orbit is definitive Tok1985
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 3.09 +/- 0.30, 3.04, and 1.17 Msun, respectively. Mlk2012
