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

Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a
crucial avenue for unlocking the formation and evolution of exoplanetary systems,. Access to …

Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a
fundamental step towards constraining the dominant chemical processes at work and, if in …

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

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 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. High-resolution spectrographs fed by adaptive optics (AO) provide a unique
opportunity to characterize directly imaged exoplanets. Observations with such instruments …

Population studies of exoplanets are key to unlocking their statistical properties. So far, the
inferred properties have been mostly limited to planetary, orbital, and stellar parameters …

M dwarfs are common host stars to exoplanets but often lack atmospheric abundance
measurements. Late-M dwarfs are also good analogs to the youngest substellar …
