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

A high C/O ratio and weak thermal inversion in the atmosphere of exoplanet WASP-12b
The carbon-to-oxygen ratio (C/O) in a planet provides critical information about its primordial origins and subsequent evolution. A primordial C/O greater than 0.8 causes a carbide-dominatedExpand

Strong infrared emission from the extrasolar planet HD 189733b
We report detection of strong infrared thermal emission from the nearby (d = 19 pc) transiting extrasolar planet HD 189733b by measuring the flux decrement during its prominent secondary eclipse. A 6Expand

Possible thermochemical disequilibrium in the atmosphere of the exoplanet GJ 436b
The nearby extrasolar planet GJ 436b—which has been labelled as a ‘hot Neptune’—reveals itself by the dimming of light as it crosses in front of and behind its parent star as seen from Earth.Expand

A spectrum of an extrasolar planet
Of the over 200 known extrasolar planets, 14 exhibit transits in front of their parent stars as seen from Earth. Spectroscopic observations of the transiting planets can probe the physical conditionsExpand

The hottest planet
Of the over 200 known extrasolar planets, just 14 pass in front of and behind their parent stars as seen from Earth. This fortuitous geometry allows direct determination of many planetary properties.Expand

A New Search for Carbon Monoxide Absorption in the Transmission Spectrum of the Extrasolar Planet HD 209458b
We have revisited the search for carbon monoxide absorption features in transmission during the transit of the extrasolar planet HD 209458b. In 2002 August-September we acquired a total of 1077Expand

The Phase-Dependent Infrared Brightness of the Extrasolar Planet ʊ Andromedae b
The star υ Andromedae is orbited by three known planets, the innermost of which has an orbital period of 4.617 days and a mass at least 0.69 that of Jupiter. This planet is close enough to its hostExpand

THERMAL EMISSION OF WASP-14b REVEALED WITH THREE SPITZER ECLIPSES
Exoplanet WASP-14b is a highly irradiated, transiting hot Jupiter. Joshi et al. calculate an equilibrium temperature (T eq) of 1866 K for zero albedo and reemission from the entire planet, a mass ofExpand

Spitzer Observations of the Thermal Emission from WASP-43b
WASP-43b is one of the closest-orbiting hot Jupiters, with a semimajor axis of a?= 0.01526?? 0.00018?AU and a period of only 0.81?days. However, it orbits one of the coolest stars with a hot JupiterExpand
