Atmospheres of Rocky Exoplanets [PDF]
Annual Review of Astronomy and Astrophysics, 60, 1, 2022, 2021 Rocky planets are common around other stars, but their atmospheric properties remain largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming advances in observing capability, we are poised to characterize the atmospheres of dozens of rocky exoplanets in this decade.

Magnetohydrodynamical Torsional Oscillations from Thermoresistive Instability in Hot Jupiters
The Astrophysical Journal, 2023 Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in the electrical conductivity due to ohmic heating results in runaway of the atmospheric temperature.

Aerosols in Exoplanet Atmospheres [PDF]
, 2021 Observations of exoplanet atmospheres have shown that aerosols, like in the Solar System, are common across a variety of temperatures and planet types. The formation and distribution of these aerosols are inextricably intertwined with the composition and thermal structure of the atmosphere.

The Inhomogeneity Effect. III. Weather Impacts on the Heat Flow of Hot Jupiters
The Astrophysical Journal, 2023 The interior flux of a giant planet impacts atmospheric motion, and the atmosphere dictates the interior’s cooling. Here we use a non-hydrostatic general circulation model (Simulating Non-hydrostatic Atmospheres on Planets) coupled with a multi-stream ...

Repeated Cyclogenesis on Hot-Exoplanet Atmospheres with Deep Heating [PDF]
Physical Review Letters, 131, 231201, 2023, 2022 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 energy deposition at differing depths in a model tidally locked gas-giant exoplanet.

The Runaway Greenhouse Effect on Hycean Worlds
The Astrophysical Journal, 2023 Hycean worlds are a proposed subset of sub-Neptune exoplanets with substantial water inventories, liquid surface oceans, and extended hydrogen-dominated atmospheres favorable for habitability.

The Variable Detection of Atmospheric Escape around the Young, Hot Neptune AU Mic b
The Astronomical Journal, 2023 Photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight into and characterize which mechanisms drive this evolution and at what ...

Vertical structure of an exoplanet's atmospheric jet stream. [PDF]
NatureUltra-hot Jupiters, an extreme class of planets not found in our solar system, provide a unique window into atmospheric processes. The extreme temperature contrasts between their day- and night-sides pose a fundamental climate puzzle: how is energy ...

The Transiting Exoplanet Community Early Release Science Program for JWST [PDF]
Publications of the Astronomical Society of the Pacific, 2018 The James Webb Space Telescope (JWST) presents the opportunity to transform our understanding of planets and the origins of life by revealing the atmospheric compositions, structures, and dynamics of transiting exoplanets in unprecedented detail. However,
