KUI 84 In the same field with Barnard's Star.
P, T, and e have been taken by Gatewood (1973) from the astrometric Gat1973
solution. In the same field with Barnard's Star. Two astrometric
mass-ratio determinations showed B to be twice as massive as A. This
has been confirmed by Tokovinin, who finds B to be a SB, P = 34.5d. Tok1994b
A measurement published by McAlister et al. (1987) dating from McA1987b
1985.4872 was misidentified as being of KUI 84; the measurement was
actually of KUI 89 (WDS 18594-1250). In addition, an observation of
KUI 84 dating from 1988.6655 (theta = 270.6 deg, rho = 0".134) was
published by McAlister et al. (1990). The data have been reprocessed, McA1990
and we now believe the 1988.6655 measurement was spurious. Hrt1994
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.57 +/- 0.61, 1.41, and 0.58 Msun, respectively. Mlk2012
