The Kepler Space Telescope is revealing for the first time valuable constraints on the inclination distribution of planetary systems with the discovery of systems of candidate multiple transiting planets. As an ensemble, the 170 candidate multi-transiting systems discovered by Kepler reveal a large population of 3-4 small nearly-coplanar planets with periods less than 125 days (Lissauer, Ragozzine, et al. 2011). The presence of multiple transiting planets does not measure the true mutual inclinations, but transit timing and duration variations (or lack thereof), multi-Rossiter-McLaughlin, and/or exoplanet mutual events can measure or put good constraints on true mutual inclinations in individual systems (Ragozzine & Holman 2010). I will discuss the recent results from Kepler observations on the inclination distributions of different exoplanet population. I will also discuss a new method for validating candidates in multi-transiting systems that uses the coplanarity of planetary systems to minimize the probability that such candidates are false positives. A summary of our understanding of exoplanetary inclinations and implications for the formation and evolution of planetary systems will also be provided.
ESSII SOC:
It is possible that I will focus my talk on a detailed analysis of KOI-500, the Kepler system with 5 candidate planets with new results showing that all the candidates are planets and discussing the intricate three-body resonance structure seen in this system.
