  author={I. Snellen and E. Mooij and S. Albrecht},
Hot Jupiters are a class of extrasolar planet that orbit their parent stars at very short distances. They are expected to be tidally locked, which can lead to a large temperature difference between their daysides and nightsides. Infrared observations of eclipsing systems have yielded dayside temperatures for a number of transiting planets. The day–night contrast of the transiting extrasolar planet HD 189733b was ‘mapped’ using infrared observations. It is expected that the contrast between the… Expand
Bright optical day-side emission from extrasolar planet CoRoT-2b
We present our analysis of the red-channel CoRoT data of extrasolar planet CoRoT-2b. A deep secondary eclipse is detected at a level of 1.02 ±0.20 ×10 −4 , which suggests that all of theExpand
We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential physics of phase curves: orbital and viewing geometry, advection, and re-radiation. We calibrate theExpand
Kepler’s Optical Phase Curve of the Exoplanet HAT-P-7b
The Kepler mission is performing at the level required to detect Earth-size planets orbiting solar-type stars, including data for the previously known giant transiting exoplanet HAT-P-7b, which shows a smooth rise and fall of light from the planet as it orbits its star, punctuated by a drop when the planet passes behind its star.

The return of the mummy: Evidence for starlight reflected from the massive hot Jupiter τ Boo b?
Very recently, we were able to measure CO absorption features in the atmosphere of the non-transiting planet τ Boo b for the very first time. This allowed us to unravel a long-term mystery in planetExpand

Abstract The last few years has seen a dramatic increase in the number of exoplanets known and in the range of methods for characterising their atmospheric properties. At the same time, newExpand
The secondary eclipse of CoRoT-1b
The transiting planet CoRoT-1b is thought to belong to the pM-class of planets, in which the thermal emission dominates in the optical wavelengths. We present a detection of its secondary eclipse inExpand
Climate of an ultra hot Jupiter : Spectroscopic phase curve of WASP-18b with HST/WFC3
We present the analysis of a full-orbit, spectroscopic phase curve of the ultra hot Jupiter (UHJ) WASP-18b, obtained with the Wide Field Camera 3 aboard the Hubble Space Telescope. We measured theExpand
The Statistics of Albedo and Heat Recirculation on Hot Exoplanets
If both the day-side and night-side effective temperatures of a planet can be measured, it is possible to estimate its Bond albedo, 0 0.8 ?m?to estimate day-side effective temperatures, T d, andExpand
CoRoT: The first space-based transit survey to explore the close-in planet population
The CoRoT (COnvection, internal ROtation and Transiting planets) space mission was launched in the last days of 2006, becoming the first major space mission dedicated to the search for and study ofExpand

A map of the day–night contrast of the extrasolar planet HD 189733b
Observations of HD 189733, the closest of these eclipsing planetary systems, over half an orbital period are reported, from which a ‘map’ of the distribution of temperatures is constructed, indicating that energy from the irradiated dayside is efficiently redistributed throughout the atmosphere.

Hot nights on extrasolar planets: mid‐infrared phase variations of hot Jupiters
We present results from Spitzer Space Telescope observations of the mid-infrared phase variations of three short-period extrasolar planetary systems: HD 209458, HD 179949 and 51 Peg. We gatheredExpand
Infrared radiation from an extrasolar planet
A class of extrasolar giant planets—the so-called ‘hot Jupiters’ (ref. 1)—orbit within 0.05 au of their primary stars (1 au is the Sun–Earth distance). These planets should be hot and so emitExpand
Detection of Thermal Emission from an Extrasolar Planet
We present Spitzer Space Telescope infrared photometric time series of the transiting extrasolar planet system TrES-1. The data span a predicted time of secondary eclipse, corresponding to theExpand

The ultraprecise photometric space satellite MOST (Microvariability and Oscillations of STars) will provide the first opportunity to measure the albedos and scattered light curves from knownExpand
Multiwavelength Constraints on the Day-Night Circulation Patterns of HD 189733b
We present new Spitzer observations of the phase variation of the hot Jupiter HD 189733b in the MIPS 24 μm bandpass, spanning the same part of the planet's orbit as our previous observations in theExpand
The Phase-Dependent Infrared Brightness of the Extrasolar Planet ʊ Andromedae b
The 24-micrometer light curve of the Andromedae system shows a variation in phase with the orbital motion of the innermost planet, demonstrating that such planets possess distinct hot substellar (day) and cold antistellar (night) faces. Expand
The close-in extrasolar giant planets (CEGPs), AU from their parent stars, may have a large (0.05 component of optically re—ected light. We present theoretical optical photometric light curves andExpand
The hottest planet
Direct detection of thermal emission from the smallest known transiting planet, HD 149026b, that indicates a brightness temperature of 2,300 ± 200 K at 8 µm is reported, which may give rise to novel atmospheric properties yet to be investigated. Expand
