STF1523 |
xi UMa = 53 UMa = Alula Australis. A is known to have an unseen |
|
|
companion, P = 1.83y. B is a spectroscopic binary. The first binary |
|
|
star orbit was computed by Savary, a "librarian-observer" at Paris |

Observatory giving courses in "social arithmetic," i.e., statistics. |

Spectral types and masses of components assigned by ten Brummelaar et |

Preliminary Keplerian AB 2-orbit model by Soderhjelm (1999) gives |
Sod1999 |
|
good solution (failure in HIP). |
|
|
Many-body perturbations observable but not yet studied. Cf. Aa,Bb |
|

analysis in Mason et al. (1995) |

|
Both orbits are visual and spectroscopic. The orbit of the visible |
|
|
AB pair includes the secular perturbations in inclination, node, |
|
|
longitude of periastron, and K. Star B is also SB1, P = 3.98 d. |
|
|
The short-period pair has been resolved by infrared speckle |
|
|
interferometry |

HR 4375 (A component of STF1523) was misidentified as HR 4374 (B |
|
|
component) in McAlister (1978). |

An orbital analysis of xi UMa, including the AB pair, the astrometric |
|
|
companion, and the newly-discovered Bc companion, has been published |
|
|
by Mason et al. (1995). |

CHR 178 |
Bb. Abt & Biggs (1972) note variable RV. |
AbH1972 |
|
Given the typical lack of accuracy associated with astrometric orbits |
Tok2010b |
|
it is possible that in the doubling of peaks CHR 178 is actually the |
|
|
known Aa,Ab observing when the faint Ab was flaring. In this |
|
|
interpretation, the second elongated observation of CHR 178 is assumed |
|
|
to be false. |

AD: Faint T8.5 brown dwarf companion at separation ~4000au exhibits |
|
|
common proper motion. IR luminosity and color suggest that mass of |
|
|
companion 14 and 38 Mjup for system ages 2 and 8 Gyr, respectively. |
