Abstract:
Main aim of this paper is the first light curve and apsidal motion
analysis of thirteen eccentric eclipsing binaries and determination of
their basic physical properties. All of the systems were studied by
the method of period analysis of times of minima and the light curve
analysis. Many new times of minima were derived and collected from the
data obtained by the automatic, robotic or satellite telescopes. This
allows us to study the apsidal motion in these systems in detail for
the first time. From the light curve analysis the first rough
estimations of the physical properties of these systems were obtained.
