Aa,Ab: chi Dra = 44 Dra. Astrometric, interferometric, and |
|
|
spectroscopic binary. See discussion of the RV's by J. Vinter Hansen |
|
|
(Lick Obs. Bul. 19, 141, 1942). |
|

See discussion and orbital elements by Labeyrie et al. (1974). |

|
Speckle and spectroscopic orbit by Tomkin et al. (1987), used P,e |
Tom1987 |

fixed from spectroscopy. Positional elements disagree somewhat with |
|
|
those of the astrometric orbit (prior to resolution of the companion) |
|
|
by Breakiron & Gatewood (1974). |

Analyses of the spectroscopic/interferometric orbit are given by |
McA1980b |
|
McAlister (1980) and McA1980c and Tomkin et al. (1987). |
Tom1987 |
|
Hipparcos astrometric solution adopted some elements from the orbit of |
HIP1997d |
|
Tomkin et al. (1987). |
Tom1987 |
|
Pourbaix gives combined solution for this resolved SB2, yielding |
Pbx2000b |
|
orbital parallaxes and component masses. |
|
|
The Farrington et al. (2010) orbit is based on speckle plus K'-band |
CIA2010 |
|
CHARA Array separated fringe packet observations. An orbital parallax |
|
|
of 123.4+/-1.9 mas is determined. Based on the mass ratio |
|
|
determination of Nordstrom et al. (2004 A&A 418, 989), derived masses |
|
|
are 0.96+/-0.03 and 0.75+/-0.03 Msun, well below the expected masses |
|
|
for an F8IV-V and late-G/early-K dwarf pair. The aperture and method, |
|
|
8m and speckle, are set to give the resolution capability of this |
|
|
technique, which is less than classical interferometric methods. |
|
|
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 1.71 +/- 0.06, 2.07, and 1.13 Msun, respectively. |
