At the dawn of the first discovery of exoplanets orbiting sun-like stars in the mid-1990s, few believed that observations of exoplanet atmospheres would ever be possible. After the 2002 Hubble Space Telescope detection of a transiting exoplanet atmosphere, many skeptics discounted it as a one-object, one-method success. Nevertheless, the field is now firmly established, with over two dozen exoplanet atmospheres observed today. Hot Jupiters are the type of exoplanet currently most amenable to… 
Illusion and reality in the atmospheres of exoplanets
The atmospheres of exoplanets reveal all their properties beyond mass, radius, and orbit. Based on bulk densities, we know that exoplanets larger than 1.5 Earth radii must have gaseous envelopes and,

Abstract With over two dozen exoplanet atmospheres observed today, the field of exoplanet atmospheres is solidly established. The highlights of exoplanet atmosphere studies include: detection of
Atmospheric characterization of terrestrial exoplanets in the mid-infrared: biosignatures, habitability, and diversity
Exoplanet science is one of the most thriving fields of modern astrophysics. A major goal is the atmospheric characterization of dozens of small, terrestrial exoplanets in order to search for

Context. High-contrast imaging is currently the only available technique for the study of the thermodynamical and compositional properties of exoplanets in long-period orbits, comparable to the range
Atmospheric Dynamics of Hot Exoplanets
The characterization of exoplanetary atmospheres has come of age in the past decade, as astronomical techniques now allow for albedos, chemical abundances, temperature profiles and maps, rotation
The First Thousand Exoplanets: Twenty Years of Excitement and Discovery
The recent “explosion” in the number of extrasolar planets, or exoplanets, is perhaps the most exciting phenomenon in all of science. Two decades ago, no planets were known beyond the Solar System,
Observational Techniques with Transiting Exoplanetary Atmospheres
Transiting exoplanets provide detailed access to their atmospheres, as the planet’s signal can be effectively separated from that of its host star. For transiting exoplanets three fundamental
Structure of exoplanets
TLDR
The diverse range of interior structures that are both known and speculated to exist in exoplanetary systems are reviewed—from mostly degenerate objects that are more than 10× as massive as Jupiter, to intermediate-mass Neptune-like objects with large cores and moderate hydrogen/helium envelopes, to rocky objects with roughly the mass of Earth.
High-resolution spectroscopy of directly-imaged exoplanet atmospheres
Since the initial discovery of planets orbiting other stars was made almost two decades ago,1 astronomers have been interested in studying their atmospheres. Light emissions, at multiple wavelengths,

The Dynamics-Based Approach to Studying Terrestrial Exoplanets
One of the great quests of astronomy is to obtain the spectrum of a terrestrial planet orbiting within the habitable zone of its star, and the dominant challenge in doing so is to isolate the light

We survey the basic principles of atmospheric dynamics relevant to explaining existing and future observations of exoplanets, both gas giant and terrestrial. Given the paucity of data on exoplanet
TRANSITS OF EARTH-LIKE PLANETS
Transmission spectroscopy of Earth-like exoplanets is a potential tool for habitability screening. Transiting planets are present-day "Rosetta Stones" for understanding extrasolar planets because

Optical Images of an Exosolar Planet 25 Light-Years from Earth
TLDR
Optical observations of an exoplanet candidate, Fomalhaut b, show that the planet's mass is at most three times that of Jupiter; a higher mass would lead to gravitational disruption of the belt, matching predictions of its location.
Direct Imaging of Multiple Planets Orbiting the Star HR 8799

A super-Earth transiting a nearby low-mass star
TLDR
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet.

Rapid heating of the atmosphere of an extrasolar planet
TLDR
8-μm photometric observations of the planet HD 80606b during a 30-hour interval bracketing the periastron passage of its extremely eccentric 111.4-day orbit indicate the global heating rate is ∼4.5 h, in comparison with 3–5 days in Earth’s stratosphere, and a secondary eclipse for the planet is detected.
