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 consistent with the orbital period of the planet with amplitudes of 2.79+0.44 –0.62 and 3.44+0.32 –0.37 parts per million (ppm), respectively, and a difference between the dayside and the nightside planetary flux of 3.41+0.55 –0.82 ppm. We present an asteroseismic analysis of… Expand

Changing Phases of Alien Worlds: Probing Atmospheres of Kepler Planets with High-Precision Photometry
We present a comprehensive analysis of planetary phase variations, including possible planetary light offsets, using eighteen quarters of data from the Kepler space telescope. After correcting forExpand
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
HAT-P-54b: A Hot Jupiter Transiting a 0.6 M⊙ Star in Field 0 of the K2 Mission
We report the discovery of HAT-P-54b, a planet transiting a late K dwarf star in field 0 of the NASA K2 mission. We combine ground-based photometric light curves with radial velocity measurements toExpand
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-rich. This impliesExpand
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
TESS Full Orbital Phase Curve of the WASP-18b System
We present a visible-light full orbital phase curve of the transiting planet WASP-18b measured by the TESS Mission. The phase curve includes the transit, secondary eclipse, and sinusoidal modulationsExpand
Accurate parameters of the oldest known rocky-exoplanet hosting system: Kepler-10 revisited
Since the discovery of Kepler-10, the system has received considerable interest because it contains a small, rocky planet which orbits the star in less than a day. The system's parameters, announcedExpand
The Densities of Planets in Multiple Stellar Systems
We analyze the effect of companion stars on the bulk density of 29 planets orbiting 15 stars in the Kepler field. These stars have at least one stellar companion within 2", and the planets haveExpand
The astrophysics of visible-light orbital phase curves in the space age
The field of visible-light continuous time series photometry is now at its golden age, manifested by the continuum of past (CoRoT, Kepler), present (K2), and future (TESS, PLATO) space-based surveysExpand
Revised Stellar Properties of Kepler Targets for the Quarter 1-16 Transit Detection Run
We present revised properties for 196,468 stars observed by the NASA Kepler mission and used in the analysis of Quarter 1-16 (Q1-Q16) data to detect and characterize transiting planets. The catalogExpand
