Abstract Ranked near the top of the long list of exciting discoveries made with NASA's Kepler photometer is the detection of transiting circumbinary planets. In just over a year the number of such planets went from zero to seven, including a multi-planet system with one of the planets in the habitable zone (Kepler-47). We are quickly learning to better detect and characterize these planets, including the recognition of their transit timing and duration variation “smoking gun” signature. Even… Expand
Kepler: A Brief Discussion of the Mission and Exoplanet Results
INTRODUCTIONThe Kepler Mission was a PI-led NASA Discovery mission designed to determine the frequency of Earth-size and larger planets in the habitable zone (HZ) of other stars (i.e., exoplanets);Expand
Circumbinary planets whose orbits become unstable may be ejected, accreted, or even captured by one of the stars. We quantify the relative rates of these channels, for a binary of secondary star'sExpand
Constraints from Planets in Binaries
In this chapter I will discuss how planets place powerful constraints on the formation and early evolution of binary star systems. In addition, these systems demonstrate extreme modes of planetExpand
SPOTS: The Search for Planets Orbiting Two Stars. III. Complete Sample and Statistical Analysis
Binary stars constitute a large percentage of the stellar population, yet relatively little is known about the planetary systems orbiting them. Most constraints on circumbinary planets (CBPs) so farExpand
Planets transiting non-eclipsing binaries
The majority of binary stars do not eclipse. Current searches for transiting circumbinary planets concentrate on eclipsing binaries, and are therefore restricted to a small fraction of potentialExpand
Kepler-47 Circumbinary Planets obey Quantization of Angular Momentum per Unit Mass predicted by Quantum Celestial Mechanics (QCM)
The Kepler-47 circumbinary system has three known planets orbiting its binary star barycenter and therefore can provide a precision test of the Quantum Celestial Mechanics (QCM) prediction of theExpand
Study of the formation of circumbinary planets and comparison with SPHERE data
The aims of this work reside in the analysis of certain disk's features and the study of the possibility for the formation of circumbinary planets in this system through the direct comparison with observational data from the SPHERE instrument, installed in the VLT in Chile. Expand
Modelling Kepler eclipsing binaries: homogeneous inference of orbital and stellar properties
We report on the properties of eclipsing binaries from the Kepler mission with a newly developed photometric modeling code, which uses the light curve, spectral energy distribution of each binary,Expand
The primary Kepler Mission provided nearly continuous monitoring of ~200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary systems within the 105Expand
Circumbinary discs: Numerical and physical behaviour
Aims. Discs around a central binary system play an important role in star and planet formation and in the evolution of galactic discs. These circumbinary discs are strongly disturbed by the timeExpand


Kepler-16: A Transiting Circumbinary Planet
The detection of a planet whose orbit surrounds a pair of low-mass stars, comparable to Saturn in mass and size and on a nearly circular 229-day orbit around its two parent stars, suggests that the planet formed within a circumbinary disk. Expand
Kepler-47: A Transiting Circumbinary Multiplanet System
The detection of Kepler-47 establishes that close binary stars can host complete planetary systems, and reveals two small planets orbiting a pair of two low-mass stars. Expand
Circumbinary Planet Formation in the Kepler-16 System. I. N-body Simulations
The recently discovered circumbinary planets (Kepler-16 b, Kepler 34-b, Kepler 35-b) represent the first direct evidence of the viability of planet formation in circumbinary orbits. We report on theExpand
Transiting circumbinary planets Kepler-34 b and Kepler-35 b
The observed rate of circumbinary planets in this sample implies that more than ∼1% of close binary stars have giant planets in nearly coplanar orbits, yielding a Galactic population of at least several million. Expand
Building Tatooine: Suppression of the Direct Secular Excitation in Kepler Circumbinary Planet Formation
Circumbinary planetary systems recently discovered by Kepler represent an important testbed for planet formation theories. Planetesimal growth in disks around binaries has been expected to beExpand
Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System
We report the discovery and confirmation of a transiting circumbinary planet (PH1b) around KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by volunteers searching theExpand
Kepler-9: A System of Multiple Planets Transiting a Sun-Like Star, Confirmed by Timing Variations
Two Saturn-size planets show variations in the times they take to transit their star due to gravitational interaction, and six radial-velocity observations show that these two planets are the most massive objects orbiting close to the star and substantially improve the estimates of their masses.

Spin-Orbit Alignment for the Circumbinary Planet Host Kepler-16 A
Kepler-16 is an eccentric low-mass eclipsing binary with a circumbinary transiting planet. Here, we investigate the angular momentum of the primary star, based on Kepler photometry and KeckExpand
An algorithm for photometric identification of transiting circumbinary planets
ABSTRACT Transiting planets manifest themselves by a periodic dimming of their host star by afixed amount. On the other hand, light curves of transiting circumbinary (CB) planetsare expected to beExpand
How Not to Build Tatooine: The Difficulty of In Situ Formation of Circumbinary Planets Kepler 16b, Kepler 34b, and Kepler 35b
We study planetesimal evolution in circumbinary disks, focusing on the three systems Kepler 16, 34, and 35 where planets have been discovered recently. We show that for circumbinary planetesimals, inExpand
