STFA 27 49 Boo = del Boo. STTA136. A is a spectroscopic binary.
Mk III Limb-darkened diameter 2.75 +/- 0.04 mas. MkT2001
Mk III Limb-darkened diameter 2.764 +/- 0.030 mas. MkT2003
NPOI Limb-darkened diameter 2.74 +/- 0.03 mas, NOI1999
R = 10.5 +/- 0.2 \rsun.
NPOI Limb-darkened diameter 2.76 +/- 0.03 mas. NOI2001b
B is BD+33@2562.
HJL 216. HJL1986
SHY 270. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
H 6 16. MEv2010
Toyota et al. (2009) monitored the RV of the A component every 1-2
months between 2003 Mar - 2007 Nov, using a high-dispersion echelle
(precision ~10 m/s). Standard deviation of radial velocities <40 m/s
and velocities show no periodic variation. This result rejects the
association of a planet of mass > 1.8 Mjup Toy2009
