We present an analysis of the KOI-13.01 candidate exoplanet system included in the 2011 September Kepler data release. The host star is a known and relatively bright (mKP= 9.95) visual binary with a separation significantly smaller (0.8 arcsec) than the size of a Kepler pixel (4 arcsec pixel−1). The Kepler light curve shows both primary and secondary eclipses, as well as significant out-of-eclipse light-curve variations. We confirm that the transit occurs round the brighter of the two stars. We… Expand

SOPHIE velocimetry of Kepler transit candidates , VI. An additional companion in the KOI-13 system
We report the discovery of a new stellar companion in the KOI-13 system. KOI-13 is composed of two fast-rotating A-type stars of similar magnitude. One of these two stars hosts a transiting planetExpand
Rapid rotators revisited: absolute dimensions of KOI-13
We analyse Kepler light-curves of the exoplanet KOI-13b transiting its moderately rapidly rotating (gravity-darkened) parent star. A physical model, with minimal ad hoc free parameters, reproducesExpand
We conducted a comprehensive search for optical phase variations of all close-in (a/R{sub *} 1), so we conclude that they are likely to be self-luminous objects rather than planets. The other sixExpand
Atmospheric Characterization of the Hot Jupiter Kepler-13Ab
Kepler-13Ab (= KOI-13.01) is a unique transiting hot Jupiter. It is one of very few known short-period planets orbiting a hot A-type star, making it one of the hottest planets currently known. TheExpand
Confirmation of hot jupiter Kepler-41B via phase curve analysis
We present high precision photometry of Kepler-41, a giant planet in a 1.86 day orbit around a G6V star that was recently confirmed through radial velocity measurements. We have developed a newExpand
Mapping a star with transits: orbit precession effects in the Kepler-13 system
Kepler-13b (KOI-13.01) is a most intriguing exoplanet system due to the rapid precession rate, exhibiting several exotic phenomena. We analyzed Kepler Short Cadence data up to Quarter 14, with aExpand
Qatar Exoplanet Survey: Qatar-7b—A Very Hot Jupiter Orbiting a Metal-rich F-Star
We present the discovery of Qatar-7b --- a very hot and inflated giant gas planet orbiting close its parent star. The host star is a relatively massive main sequence F-star with mass and radius MstarExpand
WTS-2 b: a hot Jupiter orbiting near its tidal destruction radius around a K dwarf
We report the discovery of WTS-2 b, an unusually close-in 1.02-d hot Jupiter (M-P = 1.12M(J), R-P = 1.30R(J)) orbiting a K2V star, which has a possible gravitationally bound M-dwarf companion at 0.6Expand
Characterizing the Cool KOIs. VII. Refined Physical Properties of the Transiting Brown Dwarf LHS 6343 C
We present an updated analysis of LHS 6343, a triple system in the Kepler field which consists of a brown dwarf transiting one member of a widely-separated M+M binary system. By analyzing the fullExpand
Discovery of XO-6b: a hot Jupiter transiting a fast rotating F5 star on an oblique orbit
Only a few hot Jupiters are known to orbit around fast rotating stars. These exoplanets are harder to detect and characterize and may be less common than around slow rotators. Here, we report theExpand


Estimating transiting exoplanet masses from precise optical photometry
We present a theoretical analysis of the optical light curves (LCs) for short-period high-mass transiting extrasolar planet systems. Our method considers the primary transit, the secondary eclipse,Expand
We use the KOI-13 transiting star-planet system as a test case for the recently developed BEER algorithm, aimed at identifying non-transiting low-mass companions by detecting the photometricExpand
KOI-13.01, a planet-sized companion in an optical double star, was announced as one of the 1235 Kepler planet candidates in 2011 February. The transit curves show significant distortion that wasExpand
A Third Hot White Dwarf Companion Detected by Kepler
We have found a system listed in the Kepler Binary Catalog (3.273 day period; Prsa et al. 2010) that we have determined is comprised of a low-mass, thermally-bloated, hot white dwarf orbiting an AExpand
Detection of Planetary Emission from the Exoplanet TrES-2 Using Spitzer/IRAC

The Kepler Light Curve of HAT-P-7
We present an analysis of the early Kepler observations of the previously discovered transiting planet HAT-P-7b. The light curve shows the transit of the star, the occultation of the planet, and theExpand
Thermal emission from WASP-33b, the hottest known planet
We report ground-based observations at 0.91 μm of the occultation of the hot Jupiter WASP-33b by its A5 host star. We measure the planet to be 0.109 ± 0.030 per cent as bright as its host star atExpand
Pre-Spectroscopic False Positive Elimination of Kepler Planet Candidates

Measurement of the Spin-Orbit Misalignment of KOI-13.01 from its Gravity-Darkened Kepler Transit Lightcurve
We model the asymmetry of the KOI-13.01 transit lightcurve assuming a gravity-darkened rapidly rotating host star in order to constrain the system's spin-orbit alignment and transit parameters. WeExpand
