I 7 The 94-yr orbit by Heintz (1995) plus the HIP parallax gives Hei1995
impossibly small mass-sum. Probably both a and P are much larger (no
orbit for another century), but motion should be followed.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 0.43 +/- 0.23, 1.54, and 0.76 Msun, respectively. Mlk2012
