Asymmetric Orbital Distribution near Mean Motion Resonance: Application to Planets Observed by Kepler and Radial Velocities
Ji-Wei Xie
Many multiple-planet systems have been found by the Kepler transit survey and various radial velocity (RV) surveys. Kepler planets show an asymmetric feature, namely, there are sma…
Transit Timing Variation of Near-Resonance Planetary Pairs. II. Confirmation of 30 planets in 15 Multiple Planet Systems
Ji-Wei Xie
Following on from Paper I in our series (Xie 2013), we report the confirmation by Transit Timing Variations (TTVs) of a further 30 planets in 15 multiple planet systems, using the…
Frequency of Close Companions among Kepler Planets - a TTV study
Ji-Wei Xie, Yanqin Wu, Yoram Lithwick
A transiting planet exhibits sinusoidal transit-time-variations (TTVs) if perturbed by a companion near a mean-motion-resonance (MMR). We search for sinusoidal TTVs in more than 26…
Transit Timing Variation of Near-Resonance Planetary Pairs: Confirmation of Twelve Multiple Planet Systems
Ji-Wei Xie
We extract Transit Timing Variation (TTV) signals for 12 pairs of transiting planet candidates that are near first-order Mean Motion Resonances (MMR), using publicly available Kepl…
Extracting Planet Mass and Eccentricity From TTV data
Yoram Lithwick, Jiwei Xie, Yanqin Wu
Most planet pairs in the Kepler data that have measured transit time variations (TTV) are near first-order mean-motion resonances. We derive analytical formulae for their TTV signa…
