Most Sun-like stars in the Galaxy reside in gravitationally bound pairs of stars (binaries). Although long anticipated, the existence of a ‘circumbinary planet’ orbiting such a pair of normal stars was not definitively established until the discovery of the planet transiting (that is, passing in front of) Kepler-16. Questions remained, however, about the prevalence of circumbinary planets and their range of orbital and physical properties. Here we report two additional transiting circumbinary… 

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.

Kepler-1661 b: A Neptune-sized Kepler Transiting Circumbinary Planet around a Grazing Eclipsing Binary

We report the discovery of a Neptune-sized ( ) transiting circumbinary planet, Kepler-1661 b, found in the Kepler photometry. The planet has a period of ∼175 days and its orbit precesses with a

Kepler 453 b - The 10th Kepler transiting circumbinary planet

We present the discovery of Kepler-453 b, a 6.2 R ⨁ ?> planet in a low-eccentricity, 240.5 day orbit about an eclipsing binary. The binary itself consists of a 0.94 and 0.195 M ☉ ?> pair of stars

No circumbinary planets transiting the tightest Kepler binaries – a possible fingerprint of a third star

The Kepler mission has yielded the discovery of eight circumbinary systems, all found around eclipsing binaries with periods greater than 7 d. This is longer than the typical eclipsing binary period

Astronomy: A new class of planet

Three examples of a new family of planets, which orbit a pair of stars rather than a single one, have been discovered. The Milky Way may contain millions of these circumbinary planets. See Letter

The curiously circular orbit of Kepler-16b

The recent discovery of a number of circumbinary planets lends a new tool to astrophysicists seeking to understand how and where planet formation takes place. Of the increasingly numerous

Evolution of circumbinary planets around eccentric binaries: The case of Kepler-34

The existence of planets orbiting a central binary star system immediately raises questions regarding their formation and dynamical evolution. Recent discoveries of circumbinary planets by the Kepler


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 the


We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest addition to the still-small family of CBPs defies the current trend of known short-period planets orbiting

Discovery of a Third Transiting Planet in the Kepler-47 Circumbinary System

Of the nine confirmed transiting circumbinary planet systems, only Kepler-47 is known to contain more than one planet. Kepler-47 b (the “inner planet”) has an orbital period of 49.5 days and a radius



Kepler Planet-Detection Mission: Introduction and First Results

The planetary findings derived from the first six weeks of observations with the Kepler mission are summarized, which include the detection of five new exoplanets, which confirm the existence of planets with densities substantially lower than those predicted for gas giant planets.

Exoplanet properties from Lick, Keck and AAT

Doppler-shift measurements with a remarkable precision of Δλ/λ=3×10−9, corresponding to velocities of 1 m s−1, have been made repeatedly of 2500 stars located within 300 light years. The observed

Detecting circumbinary planets using eclipse timing of binary stars - numerical simulations

The presence of a body in an orbit around a close eclipsing binary star manifests itself through the light time e ect influencing the observed times of eclipses as the close binary and the

KOI-126: A Triply Eclipsing Hierarchical Triple with Two Low-Mass Stars

The Kepler telescope detected a triple stellar system consisting of a low-mass binary and a poorly sampled fully convective stellar domain offering a crucial benchmark for theoretical stellar models.

Prospects of the detection of circumbinary planets with Kepler and CoRoT using the variations of eclipse timing

In close eclipsing binaries, measurements of the variations in binary's eclipse timing may be used to infer information about the existence of circumbinary objects. To determine the possibility of
