STF1781 One of the stars is probably variable. Baz1972
One component is a W UMa-type eclipsing binary. Wor1956b
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
One component is a W UMa-type eclipsing binary. A is the variable HT
Vir. Errors for orbit of Alzner (2007) provided by author (private Alz2007
comm.) With the Hipparcos parallax of 15.39 +/- 2.72 mas, the Alzner
solution yields a mass sum of 3.98Msun.
