PICASO 4.0: New Era for Modeling Brown Dwarf and Exoplanet Atmospheres

Star system: WASP-39 | Distance from the Sun: 702 light years

PICASO 4.0 is a major update to an open-source tool for simulating the atmospheres of brown dwarfs and exoplanets. The new version adds cloud modeling, photochemistry, and energy injection features, helping scientists better understand these distant worlds.
The update is motivated by recent discoveries from the JWST telescope, which revealed complex chemistry and clouds in exoplanet atmospheres. PICASO 4.0 is benchmarked against published models, including the well-studied exoplanet WASP-39b.
