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 Upcoming James Webb Space Telescope observations will allow us to study
exoplanet and brown dwarf atmospheres in great detail. The physical interpretation of these …

The computation of complex neutral/ionized chemical equilibrium compositions is invaluable
to obtain scientific insights of, for example, the atmospheres of extrasolar planets and cool …

Context. Gas giants orbiting close to hot and massive early-type stars can reach dayside
temperatures that are comparable to those of the coldest stars. These 'ultra-hot Jupiters' …

The dayside atmospheres of ultra-hot Jupiters (UHJs) are predicted to possess temperature
inversion layers with extremely high temperatures at high altitudes. We observed the …

Aims. We present a novel method for studying the thermal emission of exoplanets as a
function of orbital phase at very high spectral resolution, and use it to investigate the climate …

Context. Observations by the Kepler satellite have revealed a gap between larger sub-
Neptunes and smaller super-Earths that atmospheric escape models had predicted as an …

Ultrahot Jupiters are ideal candidates to explore with high-resolution emission spectra.
Detailed theoretical studies are necessary to investigate the range of spectra that we can …

Models of exoplanet atmospheres based on Parker wind density and velocity profiles are a
common choice in fitting spectroscopic observations tracing planetary atmospheric escape …

Ultra-hot Jupiters are highly irradiated gas giant exoplanets on close-in orbits around their
host stars. The dayside atmospheres of these objects strongly emit thermal radiation due to …
