AB: GJ 791.2 = HU Del. HST Fine Guidance Sensor data were used by |
|
|
Benedict et al. (2000) to derive perturbation orbital parameters, |
AST2000 |
|
distance, component masses, and absolute magnitudes for this nearby |
|
|
low-mass binary. Published measures are of the primary relative to the |
|
|
barycenter. The authors calculate a true semi-major axis of 108.8 |
|
|
+/- 0.7 mas, while Harrington (1971) calculates a value of 0".10. |
Hrr1971 |
|
Harrington determined a delta-m in excess of 3, in agreement with the |
|
|
HST measures. |

See Baize & Petit (1989) catalog of doubles with variable component. |

|
As the measures relative to the barycenter were cataloged as measures |
AST2000 |
|
of AB, the first measure of AB was cataloged as JNN 282. The pair is |
Jnn2014 |
|
a simple binary. Identity first suggested by Knapp. |
