Clouds in the atmosphere of the super-Earth exoplanet GJ 1214b
TLDR
A measurement of the transmission spectrum of GJ 1214b at near-infrared wavelengths is reported, sufficiently precise to detect absorption features from a high mean-molecular-mass atmosphere and rule out cloud-free atmospheric models with compositions dominated by water, methane, carbon monoxide, nitrogen or carbon dioxide.

Transiting Exoplanet Survey Satellite (TESS)
The Transiting Exoplanet Survey Satellite (TESS ) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission.Expand
The Transiting Exoplanet Survey Satellite: Simulations of planet detections and astrophysical false positives
The Transiting Exoplanet Survey Satellite (TESS) is a NASA-sponsored Explorer mission that will perform a wide-field survey for planets that transit bright host stars. Here, we predict the propertiesExpand
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
Spitzer Transit and Secondary Eclipse Photometry of GJ 436b
We report the results of infrared (8 μm) transit and secondary eclipse photometry of the hot Neptune exoplanet, GJ 436b using Spitzer. The nearly photon-limited precision of these data allows us toExpand
A continuum from clear to cloudy hot-Jupiter exoplanets without primordial water depletion
TLDR
The difference between the planetary radius measured at optical and infrared wavelengths is an effective metric for distinguishing different atmosphere types, so that strong water absorption lines are seen in clear-atmosphere planets and the weakest features are associated with clouds and hazes.

THE CLIMATE OF HD 189733b FROM FOURTEEN TRANSITS AND ECLIPSES MEASURED BY SPITZER
We present observations of six transits and six eclipses of the transiting planet system HD 189733 taken with the Spitzer Space Telescope's Infrared Array Camera (IRAC) at 8 μm, as well as aExpand
THERMAL PHASE VARIATIONS OF WASP-12b: DEFYING PREDICTIONS
We report Warm Spitzer full-orbit phase observations of WASP-12b at 3.6 and 4.5 μm. This extremely inflated hot Jupiter is thought to be overflowing its Roche lobe, undergoing mass loss and accretionExpand
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
Detection of a transit of the super-Earth 55 Cancri e with warm Spitzer
We report on the detection of a transit of the super-Earth 55 Cnc e with warm Spitzer in IRAC’s 4.5 μm band. Our MCMC analysis includes an extensive modeling of the systematic effects affecting warmExpand
