Orbital solutions and absolute elements of the eclipsing binary AY Camelopardalis.

WILLIAMON R.M., SOWELL J.R. and VAN HAMME W.

Abstract (from CDS):

New differential UBV photoelectric photometry for the eclipsing binary AY Cam is presented. The Wilson-Devinney program is used to simultaneously solve the three light curves together with previously published radial velocities. We determine absolute dimensions and estimate the age of the system. AY Cam is a detached binary consisting of two stars on the main sequence but evolved beyond their respective main-sequence life midpoints. As expected, the more massive star is the most evolved and about 145 K cooler than its less massive companion. We determine color indexes for the two stars and estimate color excesses.
