Aa,Ab: Roettenbacher et al. (2015) resolve the RS CVn binary omi Dra |
|
|
and determined a combined spectroscopic/astrometric orbit. The orbital |
|
|
parallax is 9.36 +/- 0.10 mas (106.8 +/- 1.1pc), flux ratio in H is |
|
|
370 +/- 40, the system age 3.0 +/- 0.5 Gyr. Radii are 25.1 +/- 0.3 and |
|
|
1.0 +/- 0.1 Rsun, luminosities 220 +/- 30 and 1.3 +/- 0.2 Lsun. |
|
|
Derived masses are 1.35 +/- 0.05 and 0.99 +/- 0.02 Msun. |
