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. |

R = 1.116+/-0.006 Rsun, 1.04+/-0.02 Msun L = 1.25+/-0.05 Lsun, |
|
|
