Identifying Transiting Circumbinary Planets [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractTransiting planets manifest themselves by a periodic dimming of their host star by a fixed amount. On the other hand, light curves of transiting circumbinary (CB) planets are expected to be neither periodic nor to have a single depth while in transit, making the Box-Least-Squares (BLS) transit detection method almost ineffective.

Effects of XUV radiation on circumbinary planets [PDF]

, 2014
Several circumbinary planets have recently been discovered. The orbit of a planet around a binary stellar system poses several dynamic constraints. The effects that radiation from the host stars may have on the planet atmospheres must be considered ...

The scattering outcomes of Kepler circumbinary planets: planet mass ratio

, 2017
Recent studies reveal that the free eccentricities of Kepler-34b and Kepler-413b are much larger than their forced eccentricities, implying that the scattering events may take place in their formation.

Circumbinary Planets Orbiting the Rapidly Pulsating Subdwarf B-type binary NY Vir [PDF]

, 2011
We report here the tentative discovery of a Jovian planet in orbit around the rapidly pulsating subdwarf B-type (sdB-type) eclipsing binary NY Vir. By using new determined eclipse times together with those collected from the literature, we detect that ...

New Pulse Timing Measurements of the sdBV Star CS 1246

Open Astronomy, 2017
CS 1246 is a hot subdwarf B star discovered in 2009 to exhibit a single, large-amplitude radial pulsation. An O-C diagram constructed from this mode revealed reflex motion due to the presence of a low-mass M dwarf, as well as a long-term trend consistent

Planet formation and stability in polar circumbinary discs [PDF]

Astronomy & Astrophysics, 2019
Context. Dynamical studies suggest that most circumbinary discs (CBDs) should be coplanar (i.e. the rotation vectors of the binary and the disc should be aligned). However, some theoretical works show that under certain conditions a CBD can become polar, which means that its rotation vector is orthogonal with respect to the binary orbital plane ...

The non-resonant, relativistic dynamics of circumbinary planets [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We investigate the non-resonant, 3-D (spatial) model of the hierarchical system composed of point-mass stellar (or sub-stellar) binary and a low-mass companion (a circumbinary planet or a brown dwarf). We take into account the leading relativistic corrections to the Newtonian gravity.

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.

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 ...

Early Planet Formation in Embedded Disks (eDisk). XIII. Aligned Disks with Nonsettled Dust around the Newly Resolved Class 0 Protobinary R CrA IRAS 32

The Astrophysical Journal
Young protostellar binary systems, with expected ages less than ∼10 ^5 yr, are little modified since birth, providing key clues to binary formation and evolution. We present a first look at the young, Class 0 binary protostellar system R CrA IRAS 32 from
