ENG 76 |
AB: A is an SB. B is BD+57@2241. |
|
|
Optical pair, based on study of relative motion of the components |
|
|
using the method of apparent motion parameters. |
Kiy2008 |
CIA 1 |
Aa,Ab: Farrington et al. (2010) present two possible orbits for this |
CIA2010 |
|
F8IV-V + F9IV-V pair. One is based on speckle plus K'-band CHARA Array |
|
|
separated fringe packet observations, the other is a combined solution |
|
|
including spectroscopic data. The resulting orbital parallax is |
|
|
39.8+/-4.8 mas, the masses 1.071+/-0.037 and 1.047+/-0.037 Msun. |
|
|
The aperture and method, 8m and speckle, are set to give the |
|
|
resolution capability of this technique, which is less than classical |
|
|
interferometric methods. |
|
|
Aa,Ab: Orbit determined by fitting revised Hipparcos intermediate |
|
|
astrometric data. Derived component masses are 0.47 +/- 0.22 and |
|
|
0.45 +/- 0.21 Msun. |
Ren2010 |
|
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 2.72 +/- 0.16, 2.39, and 2.38 Msun, respectively. |
Mlk2012 |
ENG 76 |
AB: Rectilinear solution by Hurowitz et al. (2014). |
