| 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 | |
