UBVRI light curves of EQ Boo
Listed in IVOA Registry (Virtual Observatory)
We present the first estimates of the relative and absolute parameters of the eclipsing binary EQ Boo based on a light-curve analysis (P=5.43d, V=8.8m).
Description
This star is simultaneously Component A of the visual binary ADS 9422 (spectral types F7V + G0V; separation of the components 1.3"; magnitude difference 0.7m). The derived disagreement between the components' physical parameters and the assumption that they have the same age can be removed if there is a fourth, late-type star in the system.
This is also able to explain the observed anomaly in the behavior of the O-C residuals at times of minima.
