"The Kepler Circumbinary Planets"
While long anticipated in both in science and science fiction, the existence of a planet orbiting a pair of normal stars was not firmly established until the discovery of Kepler-16b in the fall of 2011. Many questions soon arose about the nature of these "circumbinary" planets: What kinds of orbits, masses, and radii could they have? What kinds of binary stars can host planets? How common are they? Over the past six years, 10 more transiting Kepler circumbinary planets have been discovered, and several more candidate systems are under investigation.
Each new system has revealed a new facet of their fascinating and complex dynamics. While still few in number, the sample is now large enough that some intriguing patterns are emerging regarding the planets' radii and orbits, and their host binary star's orbital periods. In this talk I will discuss the discovery and characterization of the Kepler circumbinary planets, the emerging trends, the remarkably high fraction of systems that lie in the habitable zone, and present the latest discoveries and candidate systems.
