CRZ 2 BDK 2. G 171-58 + 2MASS J00250365+4759191. Distance 42.2 +2.0/-1.8
pc for primary, 31 +/- 6 pc for secondary. Estimated ages of
components are discrepant: 1.8-3.5 Gyr for primary, versus 0.1-0.5 Gyr
for secondary. The primary is a spectroscopic binary resolved by Hip1997a
Hipparcos, the secondary a close (~10au) L4+L4 pair, resolved by Reid Red2006b
(2006). Fah2010
HDS 56 Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.30 +/- 0.21, 1.85, and 1.10 Msun, respectively. Mlk2012
