Helium Atmospheres on Warm Neptune- and Sub-Neptune-Sized Exoplanets and Applications to GJ 436 b [PDF]

open access: yes, 2015
Warm Neptune- and sub-Neptune-sized exoplanets in orbits smaller than Mercury's are thought to have experienced extensive atmospheric evolution. Here we propose that a potential outcome of this atmospheric evolution is the formation of helium-dominated ...

Atmospheric Dynamics of Hot Exoplanets [PDF]

open access: yesAnnual Review of Earth and Planetary Sciences, 2015
The characterization of exoplanetary atmospheres has come of age in the past decade, as astronomical techniques now allow for albedos, chemical abundances, temperature profiles and maps, rotation periods, and even wind speeds to be measured. Atmospheric dynamics sets the background state of density, temperature, and velocity that determines or ...

Exploring Climate with Obliquity in a Variable-eccentricity Earth-like World

open access: yesThe Astronomical Journal, 2023
Exploring planetary systems similar to our solar system can provide a means to explore a large range of possibly temperate climates on Earth-like worlds.

The Status of Spectroscopic Data for the Exoplanet Characterisation Missions [PDF]

open access: yes, 2014
The status of laboratory spectroscopic data for exoplanet characterisation missions such as EChO is reviewed. For many molecules (eg H2O, CO, CO2, H3+, O2, O3) the data are already available.

The ARCiS framework for Exoplanet Atmospheres: The Cloud Transport Model [PDF]

open access: yes, 2019
Understanding of clouds is instrumental in interpreting current and future spectroscopic observations of exoplanets. Modelling clouds consistently is complex, since it involves many facets of chemistry, nucleation theory, condensation physics ...

The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars [PDF]

open access: yes, 2012
The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M ...

A Catalog of Exoplanet Atmospheric Retrieval Codes

open access: yesResearch Notes of the AAS, 2023
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 ...
