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 …

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 …

We report the first detection of CO emission at high spectral resolution in the day-side
infrared thermal spectrum of an exoplanet. These emission lines, found in the atmosphere of …

Abstract We present Keck Planet Imager and Characterizer (KPIC) high-resolution (R∼
35,000) K-band thermal emission spectroscopy of the ultrahot Jupiter WASP-33b. The use of …

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 …

Aims. We aim to extract the transmission spectrum of the HI Balmer lines of the ultra-hot
Jupiter (UHJ) KELT-20b/MASCARA-2b from observations and to further compare the results …

We report an attempt to detect molecular and atomic species in the atmosphere of the
ultrahot Jupiter WASP-33b using the high-resolution echelle spectrograph NEID with a …

The detection of lines in emission in planetary atmospheres provides direct evidence of
temperature inversion. We confirm the trend of ultra-hot Jupiters orbiting A-type stars that …

Hydrogen and helium transmission signals trace the upper atmospheres of hot gas-giant
exoplanets, where the incoming stellar extreme ultraviolet and X-ray fluxes are deposited …

Giant planets acquire gas, ices and rocks during the early formation stages of planetary
systems and thus inform us on the formation process itself. Proceeding from inside out …
