The influence of coronal mass ejections on the gas dynamics of the atmosphere of a “hot Jupiter” exoplanet [PDF]
Astronomy Reports, 2016 The results of three-dimensional numerical simulations of the gas dynamics of the atmosphere of a "hot Jupiter" exoplanet during the passage of a coronal mass ejection (CME) from the central star are presented. These computations assumed the parameters for the stellar wind and the CME to be typical of the solar values.

Toward Consistent Modeling of Atmospheric Chemistry and Dynamics in Exoplanets: Validation and Generalization of the Chemical Relaxation Method [PDF]
The Astrophysical Journal, 2018 Abstract Motivated by the work of Cooper & Showman, we revisit the chemical relaxation method, which seeks to enhance the computational efficiency of chemical kinetics calculations by replacing the chemical network with a handful of independent source/sink terms.

Traveling Planetary-scale Waves Cause Cloud Variability on Tidally Locked Aquaplanets
The Planetary Science Journal, 2023 Cloud cover at the planetary limb of water-rich Earth-like planets is likely to weaken chemical signatures in transmission spectra, impeding attempts to characterize these atmospheres.

A Radiative-convective Model for Terrestrial Planets with Self-consistent Patchy Clouds
The Planetary Science Journal, 2023 Clouds are ubiquitous: they arise for every solar system planet that possesses an atmosphere and have also been suggested as a leading mechanism for obscuring spectral features in exoplanet observations.

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.

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 ...

Dynamic mineral clouds on HD 189733b [PDF]
Astronomy & Astrophysics, 2017 Context. As the 3D spatial properties of exoplanet atmospheres are being observed in increasing detail by current and new generations of telescopes, the modelling of the 3D scattering effects of cloud forming atmospheres with inhomogeneous opacity structures becomes increasingly important to interpret observational data. Aims.

A Test of the Dedalus Software for Exoplanet Atmospheric Dynamics
Research Notes of the AASAbstract Studying exoplanet flow and variability requires solving atmospheric dynamics equations accurately. Here we use the shallow-water equations to evaluate and employ Dedalus 3 , a spectral method-based software package for solving differential equations.

Exoplanet winds: Modelling atmospheric dynamics via resolved spectral lines
, 2021 This thesis benchmarked a new probe of atmospheric dynamics in exoplanet atmospheres by resolving the spectral lines stemming from these far atmospheres and then modelling their line shape taking into account the broadening from atmospheric winds. This gives us a window into atmospheric winds for these far away worlds only limited by the depths of the ...
