The field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

Theoretical studies of giant planet formation suggest that substantial quantities of metals—
elements heavier than hydrogen and helium—can be delivered by solid accretion during the …

The ExoMol database (www. exomol. com) provides molecular data for spectroscopic
studies of hot atmospheres. These data are widely used to model atmospheres of …

Ground-based high-resolution and space-based low-resolution spectroscopy are the two
main avenues through which transiting exoplanet atmospheres are studied. Both methods …

Ultra-hot Jupiters are perfect targets for transmission spectroscopy. However, their
atmospheres feature strong spatial variations in temperature, chemistry, dynamics, cloud …

Ultra-hot Jupiters are tidally locked with their host stars, dividing their atmospheres into a hot
dayside and a colder nightside. As the planet moves through transit, different regions of the …

The characterization of exoplanet atmospheres has proven to be successful using high-
resolution spectroscopy. Phase curve observations of hot/ultra-hot Jupiters can reveal their …

Isotope ratios have recently been measured in the atmospheres of directly imaged and
transiting exoplanets from ground-based observations. The arrival of JWST allows us to …

This review presents an insight into our current knowledge of the atmospheres of the planets
Venus, Mars, Jupiter, Saturn, Uranus and Neptune, the satellite Titan, and those of …

ABSTRACT Most ultra-hot Jupiters (UHJs) show evidence of temperature inversions, in
which temperature increases with altitude over a range of pressures. Temperature …
