STFA 46 STTA189.
AB: A is 16 Cyg. B is BD+50@2848. A premature orbit has been computed.
Statistically the same parallax within the errors would indicate the
components are physical.
A family of possible orbital solutions are determined by Romanenko Rmn1994
(1994), with periods ranging from 124,000 to 451,000 years, using the
method of apparent motion parameters and incorporating parallax and
radial velocity information.
Based on combined astrometry, velocity information, and Hipparcos
parallax, Hauser & Marcy (1999) determine a family of possible orbits, Mrc1999
with periods ranging from 18,200 yr to 1.3 Myr, depending on the
line-of-sight separation between the components. A second family of
possible orbits are determined assuming the C component is physical
with the system.
AB: HJL 266. HJL1986
AB: SHY 95. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
AB: H 5 46. MEv2010
AB: Kiselev & Romanenko (2011) generate another set of possible PkO2011
solutions, based in part on photographic measures obtained at Pulkova
Observatory from 1960 to 2007. Periods range from 209 - 290 centuries.
Based on predicted mass sums from these various orbital elements, the
135-century solution of Hauser & Marcy (1999) appears at present to Mrc1999
give the most realistic results.
AB: B has a planet P=2.19y. Tok2014d
Asteroseismology from the Kepler data yields for Component A: KOI2015

t = 7.07+/-0.26 Gyr, Z = 0.021+/-0.002 Yi = 0.25+/-0.01 and
log g = 4.292+/-0.03. For Component B:
R = 1.116+/-0.006 Rsun, 1.04+/-0.02 Msun L = 1.25+/-0.05 Lsun,
t = 6.74+/-0.24 Gyr, Z = 0.022+/-0.003 Yi = 0.26+/-0.01 and

1.194+/-0.06 Rsun and age of 7.2+/-0.2 Gy for 16 Cyg A and for 16 Cyg B
0.945+/-0.015 Msun and 1.09+/-0.01 Rsun
Astroseismology results for the masses 1.07 +/- 0.02, 1.05 +/- 0.02 XXX2020h
