B 2601
Ross 614, aka GJ 234. Possibly first resolved by van den Bos.
B__1951a
Good resolved solution with the aid of scattered visual and IR speckle
observations. Mass-ratio calculated from pc orbit size.
Star B is the flare star V577 Mon; star A is also suspected to flare.
Lippincott (1955) orbit is based on the astrometric elements
Lip1955
combined with Baade's observation of the companion in 1955.
Combined solution from astrometry, spectroscopy, and parallax.
See Baize & Petit (1989) catalog of doubles with variable component.
Baz1989d
1986.952: combination of NS and EW 1-D IR speckle data for 1986.952
Cpb1994
1991.896: combination of data from 1991.894 and 1991.897
Cpb1994
1992.143: combination of data from 1992.141 -- 1992.146
Cpb1994
Solution includes mass and orbital parallax determination.
Sgr2000
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 0.30 +/- 0.02, 0.27, and 0.41 Msun, respectively.
