| Description | Orbital period changes of the eclipsing binaries GO Cyg and GW Cep are explained by the light time effect for the first time. New minima of the eclipsing binary AR Aur improve the predicted light time orbit. The light time orbit with the quadratic ephemeris of the binary matches the new observations of V505 Sgr better than the linear one. As the light time effect fits in corresponding OC diagrams of all four systems have been reaching extreme values, the observations of minima times in forthcoming years are highly desirable. |
