On the Abundance of Circumbinary Planets [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We present here the first observationally based determination of the rate of occurrence of circumbinary planets. This is derived from the publicly available Kepler data, using an automated search algorithm and debiasing process to produce occurrence ...

The scattering outcomes of Kepler circumbinary planets: planet mass ratio [PDF]
The Astronomical Journal, 2017 Recent studies reveal that the free eccentricities of Kepler-34b and Kepler-413b are much larger than their forced eccentricities, implying that the scattering events may take place in their formation.

Climate variations on Earth-like circumbinary planets. [PDF]
Nat Commun, 2017 AbstractThe discovery of planets orbiting double stars at close distances has sparked increasing scientific interest in determining whether Earth-analogues can remain habitable in such environments and how their atmospheric dynamics is influenced by the rapidly changing insolation.

Concealing Circumbinary Planets with Tidal Shrinkage
The Astrophysical JournalOf the 14 transiting planets that have been detected orbiting eclipsing binaries (“circumbinary planets”), none have been detected with stellar binary orbital periods shorter than 7 days, despite such binaries existing in abundance.

Photo-dynamical Analysis of Circumbinary Multi-planet System TOI-1338: A Fully Coplanar Configuration with a Puffy Planet [PDF]
The Astronomical JournalTOI-1338 is the first circumbinary planet (CBP) system discovered by TESS. It has one transiting planet at P ∼ 95 days and an outer nontransiting planet at P ∼ 215 days complemented by radial velocity (RV) observation.

Reflected eclipses on circumbinary planets [PDF]
EPJ Web of Conferences, 2011 A photometric method to detect planets orbiting around shortperiodic binary stars is presented. It is based on the detection of eclipse-signatures in the reflected light of circumbinary planets.

Instabilities in Multi-Planet Circumbinary Systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 The majority of the discovered transiting circumbinary planets are located very near the innermost stable orbits permitted, raising questions about the origins of planets in such perturbed environments.

AC Her: Evidence of the First Polar Circumbinary Planet
The Astrophysical Journal Letters, 2023 We examine the geometry of the post–asymptotic giant branch (AGB) star binary AC Her and its circumbinary disk. We show that the observations describe a binary orbit that is perpendicular to the disk with an angular momentum vector that is within 9° of ...

Modelling Circumbinary Planets: The case of Kepler-38 [PDF]
Astronomy & Astrophysics, 2014 Recently, a number of planets orbiting binary stars have been discovered by the Kepler space telescope. In a few systems the planets reside close to the dynamical stability limit.
