discov_num notes refcode
KUI 41 Ross 440. The primary is probably a flare star.
Pair often unresolved, so orbit probably eccentric with P<10y. Kui1943
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 0.74 +/- 0.21, 0.80, and 0.30 Msun, respectively. Mlk2012
