Earth’s polar night boundary layer as an analogue for dark side inversions on synchronously rotating terrestrial exoplanets [PDF]

, 2020
A key factor in determining the potential habitability of synchronously rotating planets is the strength of the atmospheric boundary layer inversion between the dark side surface and the free 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 ...

The Habitable Zone and Extreme Planetary Orbits [PDF]

, 2012
The Habitable Zone for a given star describes the range of circumstellar distances from the star within which a planet could have liquid water on its surface, which depends upon the stellar properties.

Gliese 581g as a scaled-up version of Earth: atmospheric circulation simulations

, 2011
We use three-dimensional simulations to study the atmospheric circulation on the first Earth-sized exoplanet discovered in the habitable zone of an M star.

A Test of the Dedalus Software for Exoplanet Atmospheric Dynamics

Research Notes of the AAS
Abstract 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.

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.

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.

Exoplanet phase curves: observations and theory

, 2018
Phase curves are the best technique to probe the three dimensional structure of exoplanets' atmospheres. In this chapter we first review current exoplanets phase curve observations and the particular challenges they face.

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 ...

The Effects of Irradiation on Hot Jovian Atmospheres: Heat Redistribution and Energy Dissipation

, 2012
Hot Jupiters, due to the proximity to their parent stars, are subjected to a strong irradiating flux which governs their radiative and dynamical properties.
