| HEI 7 |
The primary is the class W eclipsing SB VW Cep, P = 0.278 d. The |
|
|
light amplitude is 0.5 mag. and the light curve is variable. |
|
|
The Hershey (1975) orbit is astrometric; only the value of the |
Hry1975 |
|
semi-major axis was computed after the companion was resolved. The |
|
|
ascending node is tentatively identified from what appears to be a |
|
|
lighttime effect superimposed on intrinsic period changes in the |
|
|
eclipsing pair. |

|
BD+74@889, (mag. 7.9, G5) one degree distant, shares common proper |
|
|
motion and radial velocity. |
|
|
Pribulla & Rucinski (2006) estimate the mass of the contact pair at |
Pbl2006 |
|
1.781 Msun and the minimum mass of the wider component at 0.42 Msun. |
