The combination of observed anticorrelations 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.

متن کاملA Habitable Zone Census via Transit Timing and the Imperative for Continuing to Observe the Kepler Field
We propose a scientific program to complete a census of planets, characterizing their masses, orbital properties, and dynamical histories using continued observations of the Kepler field of view with the Kepler spacecraft in a two reaction wheel mission (subsequently referred to as Kepler-II). Even with a significantly reduced photometric precision, extending time-domain observations of this fi...
متن کاملTransit Timing Variation of Near-resonant Koi Pairs: Confirmation of 12 Multiple Planet Systems
We extract Transit Timing Variation (TTV) signals for pairs of transiting planet candidates that are near first-order Mean Motion Resonances (MMR), using publicly available Kepler lightcurves (Q0-Q9). We are able to solidly confirm the planetary nature of 12 new pairs because their TTV signals exhibit sinusoidal variations at the expected timescale and with reasonable phases. Applying the analy...
متن کاملThe Relation between the Transit Depths of Kic 12557548b & the Stellar Rotation Period
Kawahara and collaborators analyzed the transits of the candidate disintegrating Mercury-mass planet KIC 12557548b and suggested that the transit depths were correlated with the phase of the stellar rotation. We have carried out a more extensive and comprehensive analysis of the transit depths of KIC 12557548b and confirm that there is indeed a robust, statistically significant signal in the tr...
متن کاملMeasurement of Planet Masses with Transit Timing Variations Due to Synodic “chopping” Effects
Gravitational interactions between planets in transiting exoplanetary systems lead to variations in the times of transit that are diagnostic of the planetary masses and the dynamical state of the system. Here we show that synodic “chopping” contributions to these transit timing variations (TTVs) can be used to uniquely measure the masses of planets without full dynamical analyses involving dire...
