BU 989 AB: kap Peg = 10 Peg.
kap Peg Double lines have been observed in the spectrum of A. Tok2006
The SB1 with P = 5.97 d (#1329 in Batten et al., 1989) is believed to Bte1989
to be the visual component B, and a set of double lines is observed
which is ascribed to star A (Beardsley & King 1976). Bey1976
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Combined solution by Muterspaugh et al. (2006), using PHASES Mut2006
differential astrometry, iodine cell radial velocities, and published
visual and speckle data. Mass of A is 1.549 +/- 0.050 Msun. Center of
light motion of Ba,Bb pair is seen, allowing determination of masses
for both components: 1.662 +/- 0.064 and 0.814 +/- 0.046 Msun.
Semimajor axis and error in catalog derived from their values of a
(AU) and parallax, plus errors in those quantities. No sign of
purported spectroscopic companion to A component. Original tabulated
data are listed below, including date (MJD), dRA and dDEC (mas),
errors in dRA and dDEC (microarcsec):

AB: Martin et al. (1998) derive component masses 1.561 +/- 0.197 and
2.602 +/- 0.284 Msun. Mig1998
Muterspaugh et al. (2008) combine PHASES astrometry with speckle and Mut2008
radial velocity data to derive orbits for both the AB and Ba,Bb pairs
of this triple. The parallax is determined at 28.93 +/- 0.18 mas
(distance 34.57 +/- 0.21 pc). Masses of the A, Ba, and Bb components
are 1.533 +/- 0.050, 1.646 +/- 0.074, and 0.825 +/- 0.059 Msun.
