A tunable Monte Carlo method for mixing correlated-k opacities. PRAS: polynomial reconstruction and sampling
Elspeth K. H. Lee
Mixed-gas opacities are critical for radiative transfer in stellar and substellar atmospheres. Several approaches exist to obtain net k-coefficients for arbitrary mixtures, each tr…
Beyond monoculture: Polydisperse moment methods for sub-stellar atmosphere cloud microphysics II. A three-moment gamma distribution formulation for GCM applications
Elspeth K. H. Lee, Kazumasa Ohno
Context. Understanding how the shape of cloud particle size distributions affects the atmospheric properties of sub-stellar atmospheres is a key area to explore, particularly in th…
Mineral cloud formation above magma oceans in sub-Neptune atmospheres
Elspeth K. H. Lee, Aaron Werlen, Caroline Dorn
The potential presence of a magma surface below a thick atmosphere primarily composed of hydrogen in some sub-Neptune exoplanets suggests a strong link between the interior composi…
Beyond monoculture: polydisperse moment methods for sub-stellar atmosphere cloud microphysics I. Examining properties of the exponential distribution
Elspeth K. H. Lee
Observational data provided by JWST instruments continue to challenge theories and models of cloud formation in sub-stellar atmospheres, requiring more sophisticated approaches in…
Three-dimensional dynamical evolution of cloud particle microphysics in sub-stellar atmospheres I. Description and exploring Y-dwarf atmospheric variability
Elspeth K. H. Lee, Kazumasa Ohno
Understanding of cloud microphysics and the evolution of cloud structures in sub-stellar atmospheres remains a key challenge in the JWST era. The abundance of new JWST data necessi…
