The influence of forward-scattered light in transmission measurements of (exo)planetary atmospheres

, 2012
[Abridged] The transmission of light through a planetary atmosphere can be studied as a function of altitude and wavelength using stellar or solar occultations, giving often unique constraints on the atmospheric composition.

Modeling of Exoplanet Atmospheres

, 2017
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 of unprecedented precision.

Refraction in exoplanet atmospheres: Photometric signatures, implications for transmission spectroscopy, and search in Kepler data

, 2017
Refraction deflects photons that pass through atmospheres, which affects transit light curves. Refraction thus provides an avenue to probe physical properties of exoplanet atmospheres and to constrain the presence of clouds and hazes.

Global Chemical Transport on Hot Jupiters: Insights from the 2D VULCAN Photochemical Model

The Astrophysical Journal
The atmospheric dynamics of tidally locked hot Jupiters is characterized by strong equatorial winds. Understanding the interaction between global circulation and chemistry is crucial in atmospheric studies and interpreting observations.

Atmospheric Circulation of Terrestrial Exoplanets [PDF]

, 2013
The investigation of planets around other stars began with the study of gas giants, but is now extending to the discovery and characterization of super-Earths and terrestrial planets. Motivated by this observational tide, we survey the basic dynamical principles governing the atmospheric circulation of terrestrial exoplanets, and discuss the ...

Effects of Ultraviolet Radiation on Sub-Neptune Exoplanet Hazes through Laboratory Experiments

The Planetary Science Journal
Temperate sub-Neptune exoplanets could contain large inventories of water in various phases, such as water worlds with water-rich atmospheres or even oceans.

Exoplanet atmospheres: A theoretical outlook [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWith over two dozen exoplanet atmospheres observed today, the field of exoplanet atmospheres is solidly established. The highlights of exoplanet atmosphere studies include: detection of molecular spectral features; constraints on atmospheric vertical temperature structure; detection of day-night temperature gradients; and a new numerical ...

Exoplanet Aeronomy: A Case Study of WASP-69 b’s Variable Thermosphere

The Astronomical Journal
Aeronomy, the study of Earth’s upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system planets to solar variability in the X-ray and extreme-ultraviolet ...

A Photochemical Phosphorus-Hydrogen-Oxygen Network for Hydrogen-dominated Exoplanet Atmospheres

The Astrophysical Journal
Due to the detection of phosphine (PH _3 ) in the solar system gas giants Jupiter and Saturn, PH _3 has long been suggested to be detectable in exosolar substellar atmospheres too.
