Proposal Summary:
I propose to construct radiative-convective equilibrium thermal models of the atmospheres of extrasolar giant planets and cool brown dwarfs. The models will explore the roles of condensation, convective transport of non-equilibrium species, deposition of incident solar energy, and photochemistry in controlling the reflected and emitted spectra of these objects. The work will facilitate the interpretation of observed spectra of cool brown dwarfs and aid in efforts to directly detect extrasolar giant planets around nearby stars. The proposal will discuss the similarities between the thermal structure, dynamics, and role of condensates in atmospheres of cool brown dwarfs and jovian planets. By studying the coolest of brown dwarfs we gain insight into processes acting deep within Jupiter's envelope and in the observable atmospheres of warm extrasolar giant planets.
