Özet
We present new findings about KIC 8043961. We find the effective temperatures of the components as 6900±200 K for the primary, and 6598±200 K for the secondary, while the logarithm of the surface gravities are found to be 4.06 cm s-2 and 3.77 cm s-2, respectively. Combination of the light curve with the spectroscopic orbit model results leads to a mass ratio of 1:09 ± 0:07 with an orbital inclination of 73:71±0:14 and a semi-major axis of 8:05±0:22R⊙. Masses of the primary and secondary components are calculated as 1:379 ± 0:109M⊙ and 1:513 ± 0:181M⊙, while the radii are found to be 1:806±0:084R⊙ and 2:611±0:059R⊙. In addition, we obtain a considerable light contribution (≈0.54%) of a third body. We compute a possible mass for the third body as 0:778 ± 0:002M⊙. We find that the primary component exhibits Dor type pulsations with 137 frequencies.
