Clouds and Hazes in Exoplanet Atmospheres [PDF]
, 2013 Clouds and hazes are commonplace in the atmospheres of solar system planets and are likely ubiquitous in the atmospheres of extrasolar planets as well. Clouds affect every aspect of a planetary atmosphere, from the transport of radiation, to atmospheric ...

Early Time Small-scale Structures in Hot Exoplanet Atmosphere Simulations
The Astrophysical JournalWe 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 with a resting state.

Unveiling the atmospheres of giant exoplanets with an EChO-class mission [PDF]
, 2014 More than a thousand exoplanets have been discovered over the last decade. Perhaps more excitingly, probing their atmospheres has become possible. With current data we have glimpsed the diversity of exoplanet atmospheres that will be revealed over the coming decade.

Three-dimensional radiative-hydrodynamical simulations of the highly irradiated short-period exoplanet HD 189733b [PDF]
, 2012 We present a detailed three-dimensional radiative-hydrodynamical simulation of the well known irradiated exoplanet HD189733b. Our model solves the fully compressible Navier-Stokes equations coupled to wavelength-dependent radiative transfer throughout ...

The role of boundary‐layer friction in modulating midlatitude heatwaves
Quarterly Journal of the Royal Meteorological Society, EarlyView.Boundary‐layer friction associated with different surface types plays an important role in modulating heatwaves in the midlatitudes. The main changes in heatwave features occur when locally modifying boundary‐layer friction along the jet‐stream axis. Real‐world differences in the occurrence of heatwaves between different locations in the midlatitudes ...

Hot Spot Offset Variability from Magnetohydrodynamical Thermoresistive Instability in Hot Jupiters
The Astrophysical JournalHot Jupiter (HJ) atmospheres are possibly subject to a thermoresistive instability (TRI). Such an instability may develop as the ohmic heating increases the electrical conductivity in a positive feedback loop, which ultimately leads to a runaway of the ...

Atmospheric Regimes and Trends on Exoplanets and Brown Dwarfs [PDF]
, 2020 A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance among the first and most accessible planetary layers observed from space, it is closely connected with planetary formation and evolution, surface and interior processes, and habitability of planets.

Oceanographic Considerations for Exoplanet Life Detection
Astrophysical Journal, 2019 Liquid water oceans are at the center of our search for life on exoplanets because water is a strict requirement for life as we know it. However, oceans are dynamic habitats—and some oceans may be better hosts for life than others.
