AST 2 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. Baz1989d
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. Kpp2019n
Estimated age 30-300 Myr; masses 0.19+/-0.08 and 0.05+/-0.03 Msun Jnn2014
a ~1.4au.
