Abstract

In this paper, we report the evidence for a planetary mass body orbiting the close binary star KIC 5095269. This detection arose from a search for eclipse timing variations among the more than 2,000 eclipsing binaries observed by Kepler. Light curve and periodic eclipse time variations have been analysed using Systemic and a custom Binary Eclipse Timings code based on the Transit Analysis Package which indicates a 7.70±0.08MJup7.70\pm0.08M_{Jup} object orbiting every 237.7±0.1d237.7\pm0.1d around a 1.2M1.2M_\odot primary and 0.51M0.51M_\odot secondary in an 18.6d orbit. A dynamical integration over 10710^7 years suggests a stable orbital configuration. Radial velocity observations are recommended to confirm the properties of the binary star components and the planetary mass of the companion.
