BU 932 y Vir. Variable? Mlr1956a
Only elements P, T, and a have been amended by Starikova (1980) from Sta1980a
the orbit of Heintz (1969). Hei1969a
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Measures hard to reconcile. There has been practically no change in
the last 10-12 years, yet the present position differs by some 290deg
from Burnham's discovery position in 1879. Some of the measures are
evidently spurious. VBs1954
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 13.50 +/- 8.22, 5.27, and 2.24 Msun, respectively. Mlk2012
