The abundance of refractory elements in giant planets can provide key insights into their
formation histories. Owing to the low temperatures of the Solar System giants, refractory …

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 …

Ultrahot Jupiters are gas giants that orbit so close to their host star that they are tidally
locked, causing a permanent hot dayside and a cooler nightside. Signatures of their …

Ground-based high-resolution transmission spectroscopy has emerged as a promising
technique for detecting chemicals in transiting exoplanetary atmospheres. Despite chemical …

Exoplanet atmospheres are inherently three-dimensional systems in which thermal/chemical
variation and winds can strongly influence spectra. Recently, the ultra-hot Jupiter WASP-76 …

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

Cross-correlation spectroscopy is an invaluable tool in the study of exoplanets. However,
aliasing between spectral lines makes it vulnerable to systematic biases. This work strives to …

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 …

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 …

Context. Ultra-hot Jupiters (UHJs), rendering the hottest planetary atmospheres, offer great
opportunities of detailed characterisation with high-resolution spectroscopy. MASCARA-4 b …
