MKT 14 | Aa,Ab: 47 Oph. Preliminary elements determined by Hummel (1997), based | |
on Mark III interferometric results. | MkT1997 | |
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic | ||
masses of 2.59 +/- 0.21, 3.02, and 1.30 Msun, respectively. | Mlk2012 | |
Wang et al. (2015) derive a combined interferometric/spectroscopic | ||
orbit, including data from the Mark III and NPOI arrays. Derived | ||
physical parameters for the Aa and Ab components include luminosities | ||
7.80 +/- 0.36 and 3.41 +/- 0.25 Lsun, radii 2.06 +/- 0.07 and | ||
1.36 +/- 0.06 Rsun. | WaX2015 |
