First Detection of Hydroxyl Radical Emission from an Exoplanet Atmosphere: High-dispersion Characterization of WASP-33b Using Subaru/IRD

Journal article

The chemical characterisation of exoplanet atmospheres plays a crucial role in profoundly enriching our comprehension of exoplanets. By deciphering the array of molecular species shaping the chemical composition of a given exoplanet atmosphere, we unlock invaluable insights into its chemical evolution, climate, physical dynamics, and even its potential for harbouring life. High-resolution molecular spectroscopy provides the fundamental data needed for robustly identifying molecules in exopla...
