LDS 93 van den Bergh reports a third star at 38@, 105.6". Bgh1958
A is exoplanet host, P=592d. B = HIP 15526 hosts exoplanets with
P=29.1d, 85.1d. Tok2014d
B is CD-29@1229.
NLTT 10636/10635 Chm2004
SHY 157. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
