discov_num notes refcode
HO 276 Not single, as previously thought.
Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000b
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.54 +/- 0.13, 2.00, and 1.10 Msun, respectively. Mlk2012
