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 …

Groundbased and spacecraft telescopic observations, combined with an intensive modeling
effort, have greatly enhanced our understanding of hot giant planets and brown dwarfs over …

Close-in giant exoplanets with temperatures greater than 2,000 K ('ultra-hot Jupiters') have
been the subject of extensive efforts to determine their atmospheric properties using thermal …

We investigate a new class of habitable planets composed of water-rich interiors with
massive oceans underlying H 2-rich atmospheres, referred to here as Hycean worlds. With …

We present an update of the open-source photochemical kinetics code VULCAN to include
C–H–N–O–S networks and photochemistry. The additional new features are advection …

Over a large range of equilibrium temperatures, clouds shape the transmission spectrum of
hot Jupiter atmospheres, yet their composition remains unknown. Recent observations show …

The magnetosphere of an exoplanet has yet to be unambiguously detected. Investigations of
star–planet interaction and neutral atomic hydrogen absorption during transit to detect …

The temperature profile of a planetary atmosphere is a key diagnostic of radiative and
dynamical processes governing the absorption, redistribution and emission of energy …

WASP-39b is a hot Saturn-mass exoplanet with a predicted clear atmosphere based on
observations in the optical and infrared. Here, we complete the transmission spectrum of the …

The atmospheric pressure–temperature profiles for transiting giant planets cross a range of
chemical transitions. Here we show that the particular shapes of these irradiated profiles for …
