HU 609 Only elements P and T have been amended from the orbit of Sta1978c
Heintz (1967). Hei1967d
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 12.01 +/- 10.65, 3.16, and 1.20 Msun, respectively. Mlk2012
A is also a 141d spectroscopic binary. B is a possible Tok2019b
spectroscopic binary (~1600d), too.
