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. |
