Exoplanet atmospheric dynamics - Observations in high spectral resolution

Despite the physical limitations of observing faraway worlds, the study of exoplanets has flourished in recent years. Yet, our insight into exoplanet atmospheres has lagged in the exoplanet boom.
Confidently resolved, minute changes in the observed spectral light allow us to trace exoplanet winds both globally and more recently with next-generation facilities in a time-resolved manner as the planet rotates. From this new 3D approach to exoplanetary studies, we can not only paint a picture of the atmospheric dynamics of these worlds but also gather insights into their formation, possibilities for moons, and more. Yet, any of these results rely heavily on our understanding of the instrument in use. I will give a quick overview of the use of ESPRESSO to study exoplanet atmospheres and current challenges.
