Transit timing observations from Kepler. IV : Confirmation of four multiple-planet systems by simple physical models
(2012-05-10)
Eighty planetary systems of two or more planets are known to orbit stars other than the Sun. For most, the data can be sufficiently explained by non-interacting Keplerian orbits, so the dynamical interactions of these ...
Transit timing observations from Kepler. II : Confirmation of two multiplanet systems via a non-parametric correlation analysis
(2012-05-10)
We present a new method for confirming transiting planets based on the combination of transit timing variations (TTVs) and dynamical stability. Correlated TTVs provide evidence that the pair of bodies is in the same physical ...
