BUP 168 Distance 1128.4".
HEN 1 Discovery designation is per Todd Henry 03/02/98.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Marcy & Moore (1989). Mrc1989
GJ 623. Martinache et al. derive dynamical masses of 0.371 +/- 0.015 Llo2007
and 0.115 +/- 0.0023 Msun. Based on IR colors and velocities, they
conclude that the pair is of low metallicity and probably old disk
population. Models do not fit all the dtaa adequately, however.
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 0.50 +/- 0.02, 0.58, and 0.40 Msun, respectively. Mlk2012
