YOLDAş, E.  and  DAL, H. A.. The chromospherically active low-mass close binary KIC 9761199. Rev. mex. astron. astrofis [online]. 2017, vol.53, n.1, pp.67-78. ISSN 0185-1101.

We present the results obtained from the analyses of KIC 9761199’s light variation acquired by the Kepler Mission. The temperature of the secondary component was found to be 3891±1 K, and the mass ratio was found to be 0.69±0.01 with an orbital inclination of 77°.4 ± 0°.1. Stellar spots separated by about 180° longitudinally were found around the latitudes of +47° and +30°. In addition, the OPEA model was derived for 94 detected flares. The plateau value was found to be 1.951±0.069 s, while the half−life value was found to be 1014 s. The flare frequency N1 was 0.01351 h−1, while the flare frequency N2 was 0.00006. Maximum flare rise time was 1118.098 s, while maximum flare total time was 6767.72 s. The chromospheric activity level of KIC 9761199 is at the expected level according to a B−V of1m .303.

Keywords : binaries: eclipsing; methods: data analysis; stars: flare; stars: individual (KIC 9761199); techniques: photometric.
