discov_num notes refcode
CHR 133 55 UMA. Primary is 2.6d SB1 (#669 in Batten et al., 1989). Bte1989
The speckle pair must be different, hence a triple.
Mass-sum in fair agreement with Liu et al. (1997) Liu1997
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
McAlister et al.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 5.89 +/- 0.40, 4.71, and 2.09 Msun, respectively. Mlk2012
