Minimum zamanın saptanmasında dalga boyunun etkisinin incelenmesi
In the present thesis, the wavelength dependence of the observed times of minima of eclipsing binaries were analysed. Many times of minima of different type eclipsing binaries in different wavelength extracted from the literature and some times of minima calculated using the orginal observation with the Kwee Van Woerden method and minima times database constructed. As man? published times of minima are generali? the average of different colors in papers. It had been necesserfly recalculate many of me minima times. A statistical work was done using rrrinima times in hard and the different behaivours of the eclipsing binaries in different colors were investigated. As a result, of this investigation, it was seen that the RS CVn systems and O-B and G spectral type systems are in a different nature in contrast to other eclipsing binary systems. It was arived that the differences between the minima times in different colors are great in these systems. KEY WORDS: Minima times. Changing Minima times according to colours, Light curve.
