Recent Kepler Results On Circumbinary Planets [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractRanked near the top of the long list of exciting discoveries made with NASA's Kepler photometer is the detection of transiting circumbinary planets. In just over a year the number of such planets went from zero to seven, including a multi-planet system with one of the planets in the habitable zone (Kepler-47).

A pair of planets around HD 202206 or a circumbinary planet?

, 2004
Long-term precise Doppler measurements with the CORALIE spectrograph reveal the presence of a second planet orbiting the solar-type star HD202206. The radial-velocity combined fit yields companion masses of m_2\sini = 17.4 M_Jup and 2.44 M_Jup, semi ...

Astronomy & Astrophysics
Young binary stars with discs provide unique laboratories for studying the earliest stages of planet formation in star-forming environments. The detection of substructure in discs around Class I protostars challenges current models of disc evolution, and

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

Kepler-16b: safe in a resonance cell

, 2013
The planet Kepler-16b is known to follow a circumbinary orbit around a system of two main-sequence stars. We construct stability diagrams in the "pericentric distance - eccentricity" plane, which show that Kepler-16b is in a hazardous vicinity to the ...

Exomoons of Circumbinary Planets

Confirmation of the first exomoon remains elusive. Although several exomoon candidates exist around single stars, there are currently no candidates around circumbinary planets (CBPs). Most circumbinary planets are thought to form far from the host binary and migrate through the protoplanetary disc.

PLANET HUNTERS: A TRANSITING CIRCUMBINARY PLANET IN A QUADRUPLE STAR SYSTEM [PDF]

The Astrophysical Journal, 2013
We report the discovery and confirmation of a transiting circumbinary planet (PH1b) around KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by volunteers searching the first six Quarters of publicly available Kepler data as part of the Planet Hunters citizen science project.

On the Orbital Evolution of Binaries with Polar Circumbinary Disks

The Astrophysical Journal Letters
Binaries occur in many astrophysical systems, from young protostellar binaries in star-forming regions to supermassive black hole binaries in galaxy centers.
