Apsidal motion in eccentric eclipsing binary WW Camelopardalis.

WOLF M., KOTKOVA L., KOCIAN R., DREVENY R. and HANZL D.

Abstract (from CDS):

WW Camelopardalis is a relatively bright eclipsing binary system with a slightly eccentric orbit. A dozen of its new eclipse times were measured as part of our long-term observational project of eccentric eclipsing binaries. Based on a new solution of the current O - C diagram, we found for the first time an apsidal motion in good agreement with theory. Its period is about 370±50 years. The determined internal structure constant is close to the theoretically expected value. The relativistic effect is significant, being about 13% of the total apsidal motion rate.
