A Comprehesive Study of the Kepler Triples via Eclipse Timing Variation Analyses

We produce and analyze eclipse time variation (ETV) curves for some 2600 targeted main-field Kepler binaries. We find good to excellent evidence for a third body in 222 systems via either the light-travel-time (LTTE) or dynamical effect delays. In this seminar lecture I present (i) our improved dynamical model for describing the third-body perturbations on the ETV of a given binary (in an analytic formalism) and therefore, for a better determination of the system parameters from the ETV curves; (ii) the semi-authomatic method of determining timing data quickly and uniformly with the appropriate handling of such enormous size of targets; (iii) the strict criteria introduced to identify real triples and filter out false positives; (iv) the statistical results obtained from 222 real triple systems; and, finally, (v) some interesting individual triples will also be discussed.
