Abstract

In previous work by Uytterhoeven et al. (2011) the Kepler object KIC 9204718 (HD 176843) was identified as a binary system with a d Scuti-type component. Both long- and short-cadence data were obtained from the MAST archive and analyzed. In this paper we show the results of period analysis on one quarter of short-cadence data in which were obtained two pulsation periods, the dominant of which has a period of 0.026479 day and the secondary of 0.029068 day, respectively. We also present the interesting light curve of the object over several quarters of long-cadence data sets.
