Analytic orbit propagation for transiting circumbinary planets [PDF]
The Astrophysical Journal, 2015 The herein presented analytical framework fully describes the motion of coplanar systems consisting of a stellar binary and a planet orbiting both stars on orbital as well as secular timescales.

TOI-1338: TESS’ First Transiting Circumbinary Planet [PDF]
The Astronomical Journal, 2020 We report the detection of the first circumbinary planet (CBP) found by Transiting Exoplanet Survey Satellite (TESS). The target, a known eclipsing binary, was observed in sectors 1 through 12 at 30 minute cadence and in sectors 4 through 12 at 2 minute cadence. It consists of two stars with masses of 1.1 M o˙ and 0.3 M o˙ on a slightly

Formation of Polar Terrestrial Circumbinary Planets [PDF]
The Astrophysical Journal Letters, 2021 Abstract All circumbinary planets (CBPs) currently detected are in orbits that are almost coplanar to the binary orbit. While misaligned CBPs are more difficult to detect, observations of polar-aligned circumbinary gas and debris disks around eccentric binaries suggest that polar planet formation may be possible.

The Astrophysical Journal Letters, 2023 Mutually misaligned circumbinary planets may form in a warped or broken gas disk or from later planet–planet interactions. With numerical simulations and analytic estimates we explore the dynamics of two circumbinary planets with a large mutual ...

Follow‐up observations of the binary system γ Cep
Astronomische Nachrichten, Volume 343, Issue 5, June 2022., 2022 Abstract We present follow‐up imaging and spectroscopic observations of the exoplanet host star γ Cep A, and of its low‐mass stellar companion γ Cep B. We used the lucky‐imager AstraLux at the Calar Alto observatory to follow the orbital motion of the companion around its primary, whose radial velocity (RV) was determined with spectra of the star ...

Birth environment of circumbinary planets: are there circumbinary planets on inclined orbits? [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The distribution of the orbital inclination angles of circumbinary planets (CBPs) is an important scientific issue, and it is of great significance for estimating the occurrence rate of CBPs and studying their formation and evolution.

Parking planets in circumbinary discs [PDF]
Astronomy & Astrophysics, 2021 The Kepler space mission has discovered about a dozen planets orbiting around binary stars systems. Most of these circumbinary planets lie near their instability boundaries, at about three to five binary separations. Past attempts to match these final locations through an inward migration process were only shown to be successful for the Kepler-16 ...

An automated method to detect transiting circumbinary planets [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACTTo date a dozen transiting ‘Tatooines’ or circumbinary planets (CBPs) have been discovered, by eye, in the data from the Kepler mission; by contrast, thousands of confirmed circumstellar planets orbiting around single stars have been detected using automated algorithms.

Circumbinary Habitable Zones in the Presence of a Giant Planet
Frontiers in Astronomy and Space Sciences, 2021 Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions.
