Light Curve and Period Change Analysis of KIC3347485.

TOKBAY D.E. and YAKUT K.

Abstract (from CDS):

High precision photometry with the space-based Kepler telescope offers an opportunity to analyze the physical processes occurring in stars in detail. In this study, we examined the light curve of the Kepler binary system KIC 3347485, which is a semi-detached binary system. We calculated minima and maxima times of four years of Kepler observation of this system using our newly developed Python code. We did period change analysis (O - C) of this system, and we discuss the existence of a possible third or even fourth component.
