CHR 39 Aa,Ab. 44 Vir. Rapid binary.
1991.3921: This interferometric system has now completed nearly 180deg
of revolution since its discovery in 1984. A preliminary
determination of orbital elements yields a low-eccentricity orbit with
a period of 15.7 years. Absolute quadrant determinations based on
reanalysis of earlier speckle data have ruled out a possible short-
period high-eccentricity orbit. A more complete orbital analysis is in
progress.
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 3.41 +/- 0.75, 3.58, and 2.00 Msun, respectively. Mlk2012
