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 |

purported spectroscopic companion to A component. Original tabulated |

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. |
