The Resilience of Habitable Climates Around Circumbinary Stars

open access: yesJournal of Geophysical Research E: Planets, 2020
Abstract Here we use a 3‐D climate system model to study the habitability of Earth‐like planets orbiting in circumbinary systems. In the most extreme cases, Earth‐like planets in circumbinary systems could experience variations in the incident stellar flux of up to ~50% on ~100‐day timescales.

Photo-dynamical Analysis of Circumbinary Multi-planet System TOI-1338: A Fully Coplanar Configuration with a Puffy Planet [PDF]

open access: goldThe Astronomical Journal
TOI-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.

Orbital evolution of a circumbinary planet in a gaseous disk [PDF]

open access: yesEarth, Planets and Space, 2019
Sub-Jupiter classed circumbinary planets discovered in close-in binary systems have orbits just beyond the dynamically unstable region, which is determined by the eccentricity and mass ratio of the host binary stars.

Constraining the Radiation and Plasma Environment of the Kepler Circumbinary Habitable Zone Planets [PDF]

open access: bronze, 2016
The discovery of many planets using the Kepler telescope includes ten planets orbiting eight binary stars. Three binaries, Kepler-16, Kepler-47, and Kepler-453, have at least one planet in the circumbinary habitable-zone (BHZ).

Instabilities in Multi-Planet Circumbinary Systems [PDF]

open access: yesMonthly 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

open access: yesThe 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 ...

How to build Tatooine: reducing secular excitation in Kepler circumbinary planet formation [PDF]

open access: bronze, 2012
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 be inhibited interior to ~10 AU by secular excitation of high ...

Gaia's potential for the discovery of circumbinary planets [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2014
The abundance and properties of planets orbiting binary stars - circumbinary planets - are largely unknown because they are difficult to detect with currently available techniques. Results from the Kepler satellite and other studies indicate a minimum occurrence rate of circumbinary giant planets of ~10 %, yet only a handful are presently known.

Circumbinary Planet Formation in the Kepler-16 system. I. N-body Simulations [PDF]

open access: bronze, 2012
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.
