Transit timing variations for planets near eccentricity-type mean motion resonances
... We present a derivation of the transit timing variations (TTVs) of a pair of planets near the j:j − 2 second order resonance on nearly circular and nearly coplanar orbits. We show that the TTVs of ...

Transit timing observations from Kepler- III. Confirmation of four multiple planet systems by a Fourier-domain study of anticorrelated transit timing variations
... For Kepler-25 and Kepler-26, we estimate that it is 300 times more likely that the planets transit the target star than they transit an unresolved companion or background star. For Kepler-27 and Kepler-28, ...
