Abstract
Analysing the photometrical data taken from the Kepler Mission Database, the results obtained from both the One Phase Exponential Association model derived for the flare activity and the spot migration on the surface of eclipsing binary system KIC 11560447 are presented. A sinusoidal variation due to the rotation modulation is defined. There are two cool spots separated by about 100° longitudinally. It is seen that the parameters of these spotted areas such as radii, latitudes and longitudes, were varying during observing seasons. Apart from the cool spots, flare activity is also detected on the target, and 226 flares were determined with their parameters. Modelling the distribution of flare equivalent durations versus the flare total times, the Plateau parameter was found to be 1.4114 ± 0.1712 s in the logarithmic scale, while the Half-time value was found to be 2394.03 s. The frequency of flare N1, which is the number of flares per an hour in the system, was computed as 0.064454 h−1, while the flare-equivalent duration emitting per an hour, N2 frequency, was found to be 0.000058.
