PICASO 3.0: A One-Dimensional Climate Model for Giant Planets and Brown Dwarfs

Understand

Upcoming James Webb Space Telescope (JWST) observations will allow us to study exoplanet and brown dwarf atmospheres in great detail.

• The physical interpretation of these upcoming high signal-to-noise observations requires precise atmospheric models of exoplanets and brown dwarfs.
• While several one-dimensional and three-dimensional atmospheric models have been developed in the past three decades, these models have often relied on simplified assumptions like chemical equilibrium and are also often not open-source, which limits their usage and development by the wider community.
• We present a python-based one-dimensional atmospheric radiative-convective equilibrium model.
