Kepler Presearch Data Conditioning II - A Bayesian Approach to Systematic Error Correction
Jeffrey C. Smith, Martin C. Stumpe, Jeffrey E. Van Cleve +8
With the unprecedented photometric precision of the Kepler Spacecraft, significant systematic and stochastic errors on transit signal levels are observable in the Kepler photometri…
Kepler Presearch Data Conditioning I - Architecture and Algorithms for Error Correction in Kepler Light Curves
Martin C. Stumpe, Jeffrey C. Smith, Jeffrey E. Van Cleve +8
Kepler provides light curves of 156,000 stars with unprecedented precision. However, the raw data as they come from the spacecraft contain significant systematic and stochastic err…
Transit Timing Observations from Kepler: III. Confirmation of 4 Multiple Planet Systems by a Fourier-Domain Study of Anti-correlated Transit Timing Variations
Jason H. Steffen, Daniel C. Fabrycky, Eric B. Ford +45
We present a method to confirm the planetary nature of objects in systems with multiple transiting exoplanet candidates. This method involves a Fourier-Domain analysis of the devia…
Transit Timing Observations from Kepler: II. Confirmation of Two Multiplanet Systems via a Non-parametric Correlation Analysis
Eric B. Ford, Daniel C. Fabrycky, Jason H. Steffen +48
We present a new method for confirming transiting planets based on the combination of transit timingn variations (TTVs) and dynamical stability. Correlated TTVs provide evidence th…
Transit Timing Observations from Kepler: IV. Confirmation of 4 Multiple Planet Systems by Simple Physical Models
Daniel C. Fabrycky, Eric B. Ford, Jason H. Steffen +31
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, s…
