Description

In this study, we present the results obtained from the analysis of KOI-7234's photometric data obtained by the Kepler satellite. For the first time in the literature, the light curve analysis of the system was carried out and it seems that the system was composed of two low mass components with the masses of 0.574 M-circle dot and 0.442 M-circle dot in radii of 0.598 R-circle dot and 0.529 R-circle dot with the semi-major axis of 17.390 R-circle dot. In total, 195 flares have been detected from the short cadence data. Over these parameters, two different OPEA models were obtained for the system, and Plateau values were calculated as 1.578 +/- 0.117 s for the first model and 1.735 +/- 0.099 s for the second, while the half-time values were calculated as 1826.87 s and 1138.10 s. The general flare frequency of the system was calculated as 0.02345 h(-1).
