Sculpting the circumbinary planet size distribution through resonant interactions with companion planets [PDF]

open access: yes, 2022
Resonant locking of two planets is an expected outcome of convergent disc migration. The planets subsequently migrate together as a resonant pair. In the context of circumbinary planets, the disc is truncated internally by the binary.

HD 143006: circumbinary planet or misaligned disc? [PDF]

open access: yes, 2021
Misalignments within protoplanetary discs are now commonly observed, and features such as shadows in scattered light images indicate departure from a co-planar geometry.

TOI-1338: TESS’ First Transiting Circumbinary Planet [PDF]

open access: yesAstronomical 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 ...

BEBOP III. Observations and an independent mass measurement of Kepler-16 (AB) b -- the first circumbinary planet detected with radial velocities [PDF]

open access: yes, 2021
The radial velocity method is amongst the most robust and most established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their relatively high occurrence rates.

Follow‐up observations of the binary system γ Cep

open access: yesAstronomische 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 ...

Planet migration in massive circumbinary discs [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
Most stars are in multiple systems, with the majority of those being binaries. A large number of planets have been confirmed in binary stars and therefore it is important to understand their formation and dynamical evolution.

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

open access: yesAstronomical Journal, 2020
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 period of only 35 yr. The precession causes the alignment of

Creep Tide Model for the 3-Body Problem. The rotational evolution of a circumbinary planet [PDF]

open access: yes, 2021
We present a tidal model for treating the rotational evolution in the general three-body problem with arbitrary viscosities, in which all the masses are considered to be extended and all the tidal interactions between pairs are taken into account.

Three-dimensional Orbit of AC Her Determined: Binary-induced Truncation Cannot Explain the Large Cavity in This Post-AGB Transition Disk

open access: yesThe Astrophysical Journal, 2023
Some evolved binaries, namely post–asymptotic giant branch (AGB) binaries, are surrounded by stable and massive circumbinary disks similar to protoplanetary disks found around young stars. Around 10% of these disks are transition disks: they have a large

The EBLM project – VII. Spin–orbit alignment for the circumbinary planet host EBLM J0608-59 A/TOI-1338 A [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
A dozen short-period detached binaries are known to host transiting circumbinary planets. In all circumbinary systems so far, the planetary and binary orbits are aligned within a couple of degrees.
