  author={Nikku Madhusudhan and Heather A. Knutson and Jonathan J. Fortney and Travis S. Barman},
Exoplanetary discoveries in the past two decades have unveiled an astonishing diversity in the physical characteristics of exoplanetary systems, including their orbital properties, masses, radii, equilibrium temperatures, and stellar hosts. Exoplanets known today range from gasgiants to nearly Earth-size planets, and some even in the habitable zones of their host stars. Recent advances in exoplanet observations and theoretical methods are now leading to unprecedented constraints on the… 
Exoplanetary Atmospheres—Chemistry, Formation Conditions, and Habitability
The theory of atmospheric chemistry in all classes of exoplanets discovered to date is reviewed, from highly irradiated gas giants, ice giants, and super-Earths, to directly imaged giant planets at large orbital separations.

Exoplanetary science is on the verge of an unprecedented revolution. The thousands of exoplanets discovered over the past decade have most recently been supplemented by discoveries of potentially
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
Detecting the atmosphere of exoplanets using high resolution spectroscopy
The planetary science as an astrophysics branch has been in a fair development in the last decades. Unmanned missions have visited all the planets of the solar system, most of the moons and some of
The search for signs of life on exoplanets at the interface of chemistry and planetary science
The exciting frontier for biosignature gas ideas is not in the study of biology itself, which is inevitably rooted in Earth’s geochemical and evolutionary specifics, but in the interface of chemistry and planetary physics.

Highlights in the study of exoplanet atmospheres
The most productive, and at times novel, methods used to probe exoplanet atmospheres are summarized; some of the most interesting results obtained are highlighted; and various broad theoretical topics in which further work could pay significant dividends are suggested.
Detection of neutral atomic species in the ultra-hot Jupiter WASP-121b
The class of ultra-hot Jupiters comprises giant exoplanets undergoing intense irradiation from their host stars. They have proved to be a particularly interesting population for their orbital and
The composition of hot Jupiter atmospheres assembled within chemically evolved protoplanetary discs
The radial-dependent positions of snowlines of abundant oxygen- and carbon-bearing molecules in protoplanetary discs will result in systematic radial variations in the C/O ratios in the gas and ice.
Geometric effects on the flux and polarization signals of Jupiter-like exoplanets.
Polarimetry has already played an important role in the characterization of planets within the solar system and is expected to prove useful in the detection and characterization of exoplanets. The
