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

Measurements of the atmospheric carbon (C) and oxygen (O) relative to hydrogen (H) in hot
Jupiters (relative to their host stars) provide insight into their formation location and …

Constraining planet formation based on the atmospheric composition of exoplanets is a
fundamental goal of the exoplanet community. Existing studies commonly try to constrain …

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 …

Ground-based high-resolution spectroscopy (HRS) has detected numerous chemical
species and atmospheric dynamics in exoplanets, most notably ultrahot Jupiters (UHJs) …

Context. WASP-121 b is a hot Jupiter that was recently found to possess rich emission (day
side) and transmission (limb) spectra, suggestive of the presence of a multitude of chemical …

The temperature of an atmosphere decreases with increasing altitude, unless a shortwave
absorber that causes a temperature inversion exists. Ozone plays this role in the Earth's …

Context. Ultra-hot Jupiters are excellent laboratories for the study of exoplanetary
atmospheres. WASP-121b is one of the most studied; many recent analyses of its …

The present-day envelope of gaseous planets is a relic of how these giant planets originated
and evolved. Measuring their elemental composition therefore presents a powerful …

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