Planets in Binaries: Formation and Dynamical Evolution

Galaxies, 2019
Binary systems are very common among field stars, yet the vast majority of known exoplanets have been detected around single stars. While this relatively small number of planets in binaries is probably partly due to strong observational biases, there is,

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

, 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 ...

Kepler-47: A Transiting Circumbinary Multi-Planet System [PDF]

, 2012
We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times that of the Earth, respectively. The binary star consists of a Sun-like star and

Planet migration in massive circumbinary discs

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT 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. We perform simulations to investigate the migration of wide-orbit giant planets (semimajor axis 100 au)

Habitability Properties of Circumbinary Planets

The Astronomical Journal, 2017
Abstract It is shown that several habitability conditions (in fact, at least seven such conditions) appear to be fulfilled automatically by circumbinary planets of main-sequence stars (CBP-MS), whereas on Earth, these conditions are fulfilled only by chance.

FORMATION OF CIRCUMBINARY PLANETS IN A DEAD ZONE [PDF]

The Astrophysical Journal, 2013
Circumbinary planets have been observed at orbital radii where binary perturbations may have significant effects on the gas disk structure, on planetesimal velocity dispersion, and on the coupling between turbulence and planetesimals. Here, we note that the impact of all of these effects on planet formation is qualitatively altered if the circumbinary ...

Near-Infrared Imaging Polarimetry of Inner Region of GG Tau A Disk

, 2016
By performing non-masked polarization imaging with Subaru/HiCIAO, polarized scattered light from the inner region of the disk around the GG Tau A system was successfully detected in the $H$ band with a spatial resolution of approximately 0.07$\arcsec ...

On the migration of protoplanets embedded in circumbinary disks

, 2007
We present the results of hydrodynamical simulations of low mass protoplanets embedded in circumbinary accretion disks. The aim is to examine the migration and long term orbital evolution of the protoplanets, in order to establish the stability ...

Terrestrial Planet Formation Surrounding Close Binary Stars [PDF]

, 2006
Disk material has been observed around both components of some young close binary star systems. It has been shown that if planets form at the right places within such disks, they can remain dynamically stable for very long times.

Regions of Dynamical Stability for Discs and Planets in Binary Stars of the Solar Neighborhood

, 2012
Using the results of Pichardo \et (2005,2008), we determine regions of dynamical stability where planets (or discs in general) could survive in stable orbits around binary stellar systems.
