Özet
We present the new findings from the light variation of KIC 7671594. We have analyzed the light curve of the system, which is likely a low-mass eclipsing close binary. We have detected a spotted active region migration on the active component. This spotted active region on the stellar surface appears to be stable during the first 2.70years, but it exhibits rapid migration during the last 0.85years of the observing season. The OPEA model was derived using 1128 flares and their corresponding parameters. In the model, the Plateau value was found to be 2.46703 +/- 0.25234s, and the half-life was calculated as 7332.28s. The flare N-1 frequency was determined to be 0.03719 h(-1), while N-2 was found to be 0.00028. We have concluded that KIC 7671594 is likely a low-mass eclipsing binary system with a main sequence component that possesses an active region covered by some cool spots around its co-rotation latitude.
