Abstract

The detached eclipsing binary system AG Per was observed at Ege University Observatory on 12 nights from December 1974 to December 1975. Approximately 460 observations were obtained in each yellow and blue. AG Per has long been known to have an apsidal motion and eccentricities. New apsidal motion parameters based on the author's observations and all of the other minima are given. Solutions for its orbital elements were carried out using three different procedures: the Kitamura method, Wood triaxial ellipsoid model and Kopal's Fourier analysis method in the frequency-domain. By use of the available spectroscopic data for AG Per, the observational apsidal motion constant has been calculated.
