GJ 436b is a warm—approximately 800 kelvin—exoplanet that periodically eclipses its low-mass (half the mass of the Sun) host star, and is one of the few Neptune-mass planets that is amenable to detailed characterization. Previous observations have indicated that its atmosphere has a ratio of methane to carbon monoxide that is 105 times smaller than predicted by models for hydrogen-dominated atmospheres at these temperatures. A recent study proposed that this unusual chemistry could be explained… Expand
The Transit Transmission Spectrum of a Cold Gas Giant Planet
We use solar occultations observed by the Visual and Infrared Mapping Spectrometer aboard the Cassini Spacecraft to extract the 1 to 5 micron transmission spectrum of Saturn, as if it were aExpand
A giant comet-like cloud of hydrogen escaping the warm Neptune-mass exoplanet GJ 436b
TLDR
In the ultraviolet the Neptune-mass exoplanet GJ 436b (also known as Gliese 436b) has transit depths of 56.3 ± 3.5% (1σ), far beyond the 0.69% optical transit depth, and it is inferred that the planet is surrounded and trailed by a large exospheric cloud composed mainly of hydrogen atoms. Expand
HAT-P-26b: A Neptune-mass exoplanet with a well-constrained heavy element abundance
TLDR
HAT-P-26b’s atmosphere is primordial and obtained its gaseous envelope late in its disk lifetime, with little contamination from metal-rich planetesimals, according to a detailed atmospheric study of the transiting Neptune-mass exoplanet. Expand
Trends in Atmospheric Properties of Neptune-Size Exoplanets
Precise atmospheric observations have been made for a growing sample of warm Neptunes. Here we investigate the correlations between these observations and a large number of system parameters to showExpand
Water vapour absorption in the clear atmosphere of a Neptune-sized exoplanet
TLDR
Observations of the transmission spectrum of the exoplanet HAT-P-11b from the optical wavelength range to the infrared indicate that the planetary atmosphere is predominantly clear down to an altitude corresponding to about 1 millibar, and sufficiently rich in hydrogen to have a large scale height.

HELIUM ATMOSPHERES ON WARM NEPTUNE- AND SUB-NEPTUNE-SIZED EXOPLANETS AND APPLICATIONS TO GJ 436b
Warm Neptune- and sub-Neptune-sized exoplanets in orbits smaller than Mercury’s are thought to have experienced extensive atmospheric evolution. Here we propose that a potential outcome of thisExpand
LYα TRANSIT SPECTROSCOPY AND THE NEUTRAL HYDROGEN TAIL OF THE HOT NEPTUNE GJ 436b
To date, more than 750 planets have been discovered orbiting stars other than the Sun. Two sub-classes of these exoplanets, "hot Jupiters" and their less massive counterparts "hot Neptunes," provideExpand
The metal-rich atmosphere of the exo-Neptune HAT-P-26b
Transmission spectroscopy is enabling precise measurements of atmospheric H2O abundances for numerous giant exoplanets. For hot Jupiters, relating H2O abundances to metallicities provides a powerfulExpand
A sub-Neptune exoplanet with a low-metallicity methane-depleted atmosphere and Mie-scattering clouds
With no analogues in the Solar System, the discovery of thousands of exoplanets with masses and radii intermediate between Earth and Neptune was one of the big surprises of exoplanet science. TheseExpand

Possible thermochemical disequilibrium in the atmosphere of the exoplanet GJ 436b
TLDR
The detection of planetary thermal emission from the dayside of GJ 436b at multiple infrared wavelengths during the secondary eclipse is reported, finding a high CO abundance and a substantial methane (CH4) deficiency relative to thermochemical equilibrium models for the predicted hydrogen-dominated atmosphere.

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.
