Evidence for a planetary mass third body orbiting the binary star KIC 5095269
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 7.700.08MJup object orbiting every 237.70.1d around a 1.2M primary and 0.51M secondary in an 18.6d orbit. A dynamical integration over 107 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.
