Transit spectroscopy can reveal a wealth of information about exoplanetary atmospheres, including:
Atmospheric Composition: Identifying gases such as hydrogen, helium, water vapor, methane, and carbon dioxide. Temperature and Pressure: Determining the thermal structure and pressure gradients in the atmosphere. Clouds and Hazes: Detecting the presence of aerosols that can obscure or alter the spectral signatures. Wind Patterns: Inferring atmospheric dynamics and potential weather patterns.
