Photometrically derived masses and radii of the planet and star in the TrES-2 system
(2012-12-10)
We measure the mass and radius of the star and planet in the TrES-2 system using 2.7 years of observations by the Kepler spacecraft. The light curve shows evidence for ellipsoidal variations and Doppler beaming on a period ...
Kepler-18b, c, and d : A system of three planets confirmed by transit timing variations, light curve validation, Warm-Spitzer photometry, and radial velocity measurements
(2011-11-01)
We report the detection of three transiting planets around a Sun-like star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from ...
The hot-Jupiter Kepler-17b : Discovery, obliquity from stroboscopic starspots, and atmospheric characterization
(2011-11-01)
This paper reports the discovery and characterization of the transiting hot giant exoplanet Kepler-17b. The planet has an orbital period of 1.486 days, and radial velocity measurements from the Hobby-Eberly Telescope show ...
Transit timing observations from Kepler. I. : Statistical analysis of the first four months
(2011-11-01)
The architectures of multiple planet systems can provide valuable constraints on models of planet formation, including orbital migration, and excitation of orbital eccentricities and inclinations. NASA's Kepler mission has ...
The distribution of transit durations for Kepler planet candidates and implications for their orbital eccentricities
(2011-11-01)
Doppler planet searches have discovered that giant planets follow orbits with a wide range of orbital eccentricities, revolutionizing theories of planet formation. The discovery of hundreds of exoplanet candidates by NASA's ...
