Abstract: High precision and continuous light curves obtained from the Kepler Space Telescope provide significant information about the behavior of cool star-spots. In this study, we obtain surface maps of the eclipsing binary KIC 9821078 with the help of the light curve inversion method to reveal longitudinal spot migration from Kepler long-cadence (LC) light curves. We also present an up-to-date solution from light and radial velocity curves. The inversion results find at least two dominant spot regions that migrate from lower to higher longitudes as a consequence of solar-like differential rotation.
