Determination of the elements of eclipsing variables, RW Gem and AY Cam, by Fourier analysis of their light changes

The aim of the present paper has been to present an analysis of the light curve of two eclipsing systems RW Gem and AY Cam by Fourier analysis of the light changes in the frequency domain which was developed by Kopel. In Section 1, the subject is introduced in a general way, with the intention of laying the foundation of the light curve analysis. Section 2 contains the evaluation of the empirical values of the theoretical moment Asub(2m) is demonstrated, with the equation of the condition given. Then the equations for Asub(2m) in terms of the elements of the total and the annular eclipses, including partial and annular phase of transit eclipse, follow. The analysis of the light curves of the two eclipsing binaries (RW Gem and AY Cam), the results and the discussion of the solution, are outlined in Section 3. (Auth.)
