Understanding Exoplanet Atmospheres [PDF]
The study of exoplanet atmospheres is a blossoming field. Over the past two decades, dozens of hot gas giant atmospheres have been observed using a variety of techniques with both space and ground telescopes, revealing the presence of water, the ...

Modeling of Exoplanet Atmospheres [PDF]
Spectrally characterizing exoplanet atmospheres will be one of the fastest moving astronomical disciplines in the years to come. Especially the upcoming James Webb Space Telescope (JWST) will provide spectral measurements from the near- to mid-infrared ...

Spectra as windows into exoplanet atmospheres. [PDF]
Understanding a planet’s atmosphere is a necessary condition for understanding not only the planet itself, but also its formation, structure, evolution, and habitability. This requirement puts a premium on obtaining spectra and developing credible interpretative tools with which to retrieve vital planetary information.

Simulations of idealised 3D atmospheric flows on terrestrial planets using LFRic-Atmosphere [PDF]
We demonstrate that LFRic-Atmosphere, a model built using the Met Office's GungHo dynamical core, is able to reproduce idealised large-scale atmospheric circulation patterns specified by several widely used benchmark recipes.

Exoplanet atmospheres at high spectral resolution
The spectrum of an exoplanet reveals the physical, chemical, and biological processes that have shaped its history and govern its future. However, observations of exoplanet spectra are complicated by the overwhelming glare of their host stars.

ExoGemS Detection of a Metal Hydride in an Exoplanet Atmosphere at High Spectral Resolution
Exoplanet atmosphere studies are often enriched by synergies with brown dwarf analogs. However, many key molecules commonly seen in brown dwarfs have yet to be confirmed in exoplanet atmospheres.

Nonthermal Atmospheric Escape on the Kepler-11 “Super-Earths” Driven by Stellar Wind Sputtering
Jeans escape or hydrodynamic escape is believed to dominate atmospheric loss for hot Jupiters. However, nonthermal mechanisms likely contribute substantially on hydrogen-rich “super-Earths” with relatively cold and extended atmospheres.

A Catalog of Exoplanet Atmospheric Retrieval Codes
Abstract Exoplanet atmospheric retrieval is a computational technique widely used to infer properties of planetary atmospheres from remote spectroscopic observations. Retrieval codes typically employ Bayesian sampling algorithms or machine learning approaches to explore the range of atmospheric properties (e.g., chemical composition ...

The Runaway Greenhouse on Sub-Neptune Waterworlds
The implications of the water vapor runaway greenhouse phenomenon for water-rich sub-Neptunes are developed. In particular, the nature of the postrunaway equilibration process for planets that have an extremely high water inventory is addressed. Crossing
