Hipparcos astrometric solution adopted some elements from the orbit of |
HIP1997d |
|
Duquennoy & Mayor (1991). |

|
Combined spectroscopic/interferometric orbit by Torres et al. (2002), |
Trr2002 |
|
including visibility data from the Palomar Testbed Interferometer. |
|

|
gamma = -5.841 0.037 km/sec |
|
|
KA = 28.926 0.046 km/sec |
|
|
KB = 36.72 0.21 km/sec |
|
|
dm = 1.056 0.013 mag (K band) |
|
|
1.154 0.065 mag (H band) |
|
|
parallax = 46.08 0.27 mas |
|
|
masses = 0.844 0.018 Msun |
|
|
0.6650 0.0079 Msun |
|
|
Orbit determined by fitting revised Hipparcos intermediate astrometric |
|
|
data. Derived component masses 0.84 +/- 0.05 and 0.67 +/- 0.04 Msun. |

A: Teff = 5296 +/- 19 K, M = 0.8420 +/- 0.0014 \msun. |
|
|
B: Teff = 4360 +/- 87 K, M = 0.66201 +/- 0.00076 \msun. |
|
|
Orbital parallax = 46.131 +/- 0.084 mas. |
|
|
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic |
|
|
masses of 1.58 +/- 0.05, 1.73, and 0.88 Msun, respectively. |
