A Search For Planets in Binary Systems

Recently, a new method of detecting exomoons was proposed, which involves the measurement of transit timing variations (TTV) and transit duration variations (TDV) of the host planet. Mainly, there are predictable patterns in the TTV-TDV diagrams of moon-hosting exoplanets. A larger scale version of a star-planet-moon system is a binary system with a planet in an S-type orbit around the lower-mass star. Here we perform a search of the Kepler eclipsing binaries and retrieve eclipse times and durations, in an effort to find patterns in the TTV-TDV diagrams indicative of an unseen companion.
