Organic hazes will impact JWST observations of water-rich exoplanets

Subjects

The optical properties of the organic hazes that form in water-rich exoplanet atmospheres differ from those that form in nitrogen-rich atmospheres. This difference in optical properties can have an observable effect on spectral observations of exoplanets and could impact the interpretation of current and upcoming JWST observations.
