A is a spectroscopic binary. B is CD-43@2907. AC = LDS 175. |

HIP 34065. See Allen et al. (2000) for information on metallicity, |

age, galactic orbital parameters, etc. |
|
|
AC: SHY 36. Bayesian analysis by Shaya & Olling (2011) indicates very |

high (near 100%) probability pair is physical. |

TOK 390 |
Ca,Cb: HIP 34052 = HD 53680 = HIP 34065C = GJ 264 is a spectroscopic |
|
|
and astrometric binary for which Sahlmann et al. (2011) give an orbit |
SaJ2011 |
|
with P=1688d = 4.62yr and an estimated semi-major axis of 0".15. There |
|
|
is also an astrometric orbit (Makarov et al. 2008) with P=4.11yr that |
Mkr2008 |
|
predicts theta = 327deg for the moment of our first observation. The |
|
|
binary is resolved at 0".23, dI = 4.4mag and shows some orbital |
|
|
motion. The binary makes a quadruple system together with components A |
|
|
and B (GJ 264.1 and 264) that form a 20".5 pair at 185" from C. The B |
|
|
component was also observed here and found unresolved. |
