B is a spectroscopic binary, P = 308d. |
|
|
Statistically different parallax for the components indicates they are |
|
|
non-physical. |

Mariotti et al. (1990). Poor Hipparcos solution. |
Sod1999 |

|
Hyperbolic orbit by Hopmann (1967). |
Hop1967 |
|
sigma = areal constant in the true orbit = 2.540 arcsec^2/yr |
|
|
q = periastron distance in the true orbit = 20".388 |
|
|
All hyperbolic orbits rejected from Fourth Orbit Catalog |
Wor1983 |
|
Pourbaix gives combined solution for this resolved SB2, yielding |
|
|
orbital parallaxes and component masses. |
Pbx2000b |
|
AF: Optical pair, based on study of relative motion of the components |
|
|
using the method of apparent motion parameters. |

Ba,Bb: Erroneously entered as BC, although C component is a very wide |
|
|
companion. |

0.004 days, T0 = JD2450270.220 +/- 0.011. Accurate masses are |
