| FIN 340 | AB. 1991.3926: From its discovery in 1954 through the mid-1960's, this | |
| system closed from 0".14 to 0".10 and increased in theta from 147 deg | ||
| to 172 deg. It is impossible to determine from this single speckle | ||
| measure whether the pair has gone through periastron and flipped | ||
| quadrant, but this should become obvious within the next couple of | ||
| observations. | ||
| AB: Malkov et al. (2012) derive dynamical, photometric, and | ||
| spectroscopic masses 3.37 +/- 0.76, 4.60, and 2.40 Msun, respectively. | Mlk2012 |
