discov_num notes refcode
B 194 Although Hartkopf et al. (1993) predicted a time of periastron Hrt1993
around 1989.3, we find the time of periastron to be 2006.2. The
discrepancy may be explained by three measures not published at the
time of the 1993 paper. USN2002
1990.3407: Periastron passage apparently occurred about the time of or
shortly before our first speckle observation in 1989.3. McA1990
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.43 +/- 0.86, 4.91, and 2.19 Msun, respectively. Mlk2012
