AB: the 2 Tau = 78 Tau = Chamukuy. Hyades vB 72 = HR 1412. |
|
|
Pair appears in an appendix list, not part of discoverer's regular |
|
|
numbering sequence. B is BD+15@631. |
|
|
Also variable, probably of Delta Scuti type. |

The 140.7-day SB of Ebbighausen (1959 Pub. DAO, 11, 235) is outside |
|
|
our detection window. |

Aa,Ab: Data from lunar occultation, spectroscopy, and Mark III |
|
|
astrometry are combined by Torres et al. to generate orbital elements. |
Trr1997c |
|
Distance and component masses and absolute magnitudes are derived from |
|
|
these elements. |
|
|
Period is fixed for the Armstrong et al. (2006) orbit. The resulting |
MkT2006 |
|
component masses are 2.15 +/- 0.12 Msun and 1.87 +/- 0.11 Msun. |
|
|
Aa,Ab: Orbit determined by fitting revised Hipparcos intermediate |
|
|
astrometric data. Derived component masses are 2.03 +/- 0.87 and |
|
|
1.78 +/- 0.76 Msun. |

Aa,Ab: Combined spectroscopic/astrometric solution, using data from |
|
|
Mark III interferometer plus high-resolution spectroscopy from ELODIE, |
|
|
HERMES, and CfA. Torres et al. (2011) determine an orbital parallax of |
Lmp2011 |
|
20.90 +/- 0.14 mas and component masses 2.86 +/- 0.06 and 2.16 +/- |
|
|
0.02 Msun. Effective temperatures for both components are 7800 +/- |
|
|
170K, absolute magnitues are 0.33 +/- 0.03 and 1.44 +/- 0.03 mag. |

This is a long period interferometric companion in addition to the |
|
|
spectroscopic component suggested by Griffin & Gunn (1977) to have a |
Grf1977d |
|
period of about 16 years. An estimate of Delta m = 0.76 was made by |
Dmb1991 |
|
Dombrowski (1991). |
