Bridging the Atmospheric Circulations of Hot and Warm Giant Exoplanets

J. W. Skinner, S. Wei

We perform high-resolution atmospheric flow simulations of hot and warm giant exoplanets that are tidally locked. The modeled atmospheres are representative of those on KELT-11b an…

Early-time small-scale structures in hot-exoplanet atmosphere simulations

J. W. Skinner, J. Y-K. Cho

We report on the critical influence of small-scale flow structures (e.g., fronts, vortices, and waves) that immediately arise in hot-exoplanet atmosphere simulations initialized wi…

Data availability and requirements relevant for the Ariel space mission and other exoplanet atmosphere applications

Katy L. Chubb, Séverine Robert, Clara Sousa-Silva +52

The goal of this white paper is to provide a snapshot of the data availability and data needs primarily for the Ariel space mission, but also for related atmospheric studies of exo…

Is the atmosphere of the ultra-hot Jupiter WASP-121b variable?

Quentin Changeat, Jack W. Skinner, James Y-K. Cho +12

We present a comprehensive analysis of the Hubble Space Telescope observations of the atmosphere of WASP-121 b, a ultra-hot Jupiter. After reducing the transit, eclipse, and phase-…

Neutron Star Atmosphere-Ocean Dynamics

Joonas Nättilä, James Y-K. Cho, Jack W. Skinner +2

We analyze the structure and dynamics of the plasma atmospheres and Coulomb-liquid oceans on neutron stars. Salient dynamical parameters are identified and their values estimated f…

Repeated Cyclogenesis on Hot-Exoplanet Atmospheres with Deep Heating

J. W. Skinner, J. Nättilä, J. Y-K. Cho

Most current models of hot-exoplanet atmospheres assume shallow heating, a strong day-night differential heating near the top of the atmosphere. Here we investigate the effects of…

Five key exoplanet questions answered via the analysis of 25 hot Jupiter atmospheres in eclipse

Quentin Changeat, Billy Edwards, Ahmed F. Al-Refaie +11

Population studies of exoplanets are key to unlocking their statistical properties. So far the inferred properties have been mostly limited to planetary, orbital and stellar parame…

Modons on Tidally Synchronised Extrasolar Planets

J. W. Skinner, J. Y-K. Cho

We investigate modons on tidally synchronised extrasolar planets. Modons are highly dynamic, coherent flow structures composed of a pair of storms with opposite signs of vorticity.…

Storms, Variability, and Multiple Equilibria on Hot-Jupiters

J. Y-K. Cho, J. W. Skinner, H. Th. Thrastarson

Observations of hot-Jupiter atmospheres show large variations in the location of the hot spot and the amplitude of spectral features. Atmospheric flow simulations using the commonl…

Exoplanets and the Sun

J. Y-K. Cho, H. Th. Thrastarson, T. T. Koskinen +4

We review the recent progress in understanding the jet structures on exoplanets as well as on and inside the Sun. The emphasis is on the more robust aspects of observation and nume…

Numerical Convergence of Hot-Jupiter Atmospheric Flow Solutions

J. W. Skinner, J. Y-K. Cho

We perform an extensive study of numerical convergence for hot-Jupiter atmospheric flow solutions in simulations employing a setup commonly-used in extrasolar planet studies, a res…
