Title

What Planets did Kepler Miss?

Abstract

Discovering and understanding the properties of exoplanets, or planets orbiting other stars,  is one of the great scientific quests of the 21st century. Since launching in 2009, NASA’s Kepler satellite has returned measurements for 200,000 stars along with the exoplanet candidates orbiting them. In order to correct for Kepler’s bias against small and/or long-period planets, we are developing an advanced computer model capable of inferring the true underlying architectures of exoplanetary systems. This Planetary System Simulator, generates simulated catalogs of exoplanet systems and uses Approximate Bayesian Computation over several generations to produce several estimations of the actual exoplanet population. I will explain the methods applied in this program and some of the figures I produced to test our results.
