The Role of Disc Self-Gravity in Circumbinary Planet Systems: II. Planet Evolution [PDF]

, 2017
The authors thank the referee for the comments and suggestions in their helpful report. Computer time for the simulations performed with GENESIS was provided by HPC resources of Cines under the allocation A0010406957 made by GENCI (Grand Equipement ...

Empirical Stability Criteria for 3D Hierarchical Triple Systems. I. Circumbinary Planets

The Astronomical Journal
In this work we revisit the problem of the dynamical stability of hierarchical triple systems with applications to circumbinary planetary orbits. We derive critical semimajor axes based on simulating and analyzing the dynamical behavior of 3 × 10 ^8 ...

The Influence of Tight Binaries on Protoplanetary Disk Masses

The Astronomical Journal
Binary systems are a common site of planet formation, despite the destructive effects of the binary on the disk. While surveys of planet-forming material have found diminished disk masses around binaries with medium separation (∼10–100 au), less is known

Investigating the System Configuration of Kepler-451 through Orbital Period Variations: Dynamical and Magnetic Interpretations

The Astrophysical Journal
We present an analysis of eclipse timing variations in Kepler-451 using data spanning 2004–2024 from both ground- and space-based observations. Using two data sets, Data Set A (DS-A) and Data Set B (DS-B), we constructed updated O–C diagrams. By modeling

Planetary Rhythms: Synchronous Circulation on Variably Irradiated Asynchronous Planets

The Astrophysical Journal
Tidal locking of planets to their host stars results in an atmospheric circulation with a hotspot fixed to the frame of reference of the planet. On the other hand, asynchronously rotating planets feature moving hotspots either lagging or leading the ...

Circumbinary planet study around NSVS 14256825

Journal of Physics: Conference Series, 2019
The period variability of (O-C) diagram of an eclipsing binary, NSVS 14256825, which is composed of a hot subdwarf type OB star (sdOB) and a main-sequence low-mass type M star (dM) in close orbit with period P=0.110374 days, previously showed sinusoidal ...

Sites of Planet Formation in Binary Systems. I. Evidence for Disk−Orbit Alignment in the Close Binary FO Tau

The Astronomical Journal
Close binary systems present challenges to planet formation. As binary separations decrease, so do the occurrence rates of protoplanetary disks in young systems and planets in mature systems.
