Gamma Dor: A Pulsating Component Of Kic 8043961 In A Stellar Triple System

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 +/- 0:22 R-circle dot. Masses of the primary and secondary components are calculated as 1:379 +/- 0:109 M-circle dot and 1:513 +/- 0:181 M-circle dot, while the radii are found to be 1:806 +/- 0:084 R-circle dot and 2:611 +/- 0:059 R-circle dot. In addition, we obtain a considerable light contribution (approximate to 0.54%) of a third body. We compute a possible mass for the third body as 0:778 +/- 0:002 M-circle dot. We find that the primary component exhibits gamma Dor type pulsations with 137 frequencies.
