Özet
Taking into account the results found by analyzing the Kepler data together with our new photometric observations as well as new spectroscopic observations, we present new findings about a highly eccentric detached eclipsing binary, KIC 4473933.For the primary and secondary components, we estimated that the radii of components were 0.98 R and 8.90 R , while the masses were 0.36 M and 0.74 M .Examining the ASAS data, we realized that the variation out-of-eclipses was due to cold stellar spots.When this data was phased according to the rotational period of 67.575786 d given in the literature, we detected two spot areas on the surface of the active component that exhibited 87.719 d and 94.340 d longitudinal migration movements.
