This method involves a Fourier-Domain analysis of the deviations in the transit times from a constant period that result from dynamical interactions within the system. The combination of observed anti-correlations in the transit times and mass constraints from dynamical stability allow us to claim the discovery of four planetary systems Kepler-25, Kepler-26, Kepler-27, and Kepler-28, containing eight planets and one additional planet candidate.en-UScelestial mechanicsstars: individual (KIC 4349452, KIC 9757613, KIC 5792202, KIC 6949607)methods: data analysistechniques: photometricTransit timing observations from Kepler: III.
