Doppler planet searches revealed that many giant planets orbit close to their host star or in
highly eccentric orbits. These and subsequent observations inspired new theories of planet …

The architectures of multiple planet systems can provide valuable constraints on models of
planet formation, including orbital migration, and excitation of orbital eccentricities and …

Kepler has discovered hundreds of systems with multiple transiting exoplanets which hold
tremendous potential both individually and collectively for understanding the formation and …

The Kepler mission has detected dozens of compact planetary systems with more than four
transiting planets. This sample provides a collection of close-packed planetary systems with …

We visually analyzed the transit timing variation (TTV) data of 5930 Kepler Objects of Interest
(KOIs) homogeneously. Using data from Rowe et al. and Holczer et al., we investigated …

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 …

The planet candidates discovered by the Kepler mission provide a rich sample to constrain
the architectures and relative inclinations of planetary systems within approximately 0.5 AU …

Solar system planets move on almost circular orbits. In strong contrast, many massive gas
giant exoplanets travel on highly elliptical orbits, whereas the shape of the orbits of smaller …

We conduct a uniform analysis of the transit timing variations (TTVs) of 145 planets from 55
Kepler multiplanet systems to infer planet masses and eccentricities. Eighty of these planets …

We study the orbital architecture of multi-planet systems detected by the Kepler transit
mission using N-body simulations, focusing on the orbital spacing between adjacent planets …
