|
A is SB1, P=75240d (Abt2006). |
Tok2014d |
|
B is a W UMa-type eclipsing binary. |
|
|
Star B is W UMa-type eclipsing SB2; P = 0.2678 d (Popper 1943; |
Ppp1943 |
|
Binnendijk 1955, AJ 60, 355). The RV of pair B differs by +30 km/s |
|
|
from that of star A, much more than the visual motion can effect, and |
|
|
thus does not represent the true mass-center velocity of B. The |
|
|
eclipsing period undergoes intrinsic changes considerably larger than |
|
|
a lighttime effect in the orbit AB. Attempts to identify the ascending |
|
|
node are thus unreliable: Time shifts of light minima suggest the |
|
|
first quadrant (Plaut), the RV difference the third quadrant (Heintz). |
|
|
The close approach in the visual orbit in recent years has prevented |
|
|
continued study of the eclipsing system. |
|

Malkov et al. (2012) derive dynamical, photometric, and spectroscopic |
|
|
masses of 2.19 +/- 0.15, 2.02, and 1.83 Msun, respectively. |

The B component is the W UMa type eclipsing binary i Boo. |
