High Resolution Transmission Spectroscopy as a Diagnostic for Jovian Exoplanet Atmospheres: Constraints from Theoretical Models [PDF]

, 2014
We present high resolution transmission spectra of giant planet atmospheres from a coupled 3-D atmospheric dynamics and transmission spectrum model that includes Doppler shifts which arise from winds and planetary motion. We model jovian planets covering

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.

Modelling compositional convection for applications to exoplanet atmospheres [PDF]

Characterizing the climates of exoplanets— planets orbiting other stars —advances our knowledge of atmospheric science, planetary formation, internal structures and will eventually lead to the holy grail of exoplanet science, detecting biosignatures of ...

Accelerating Chemical Kinetics for Exoplanet Atmospheres Using Neural Networks

The Astrophysical Journal
Observations increasingly reveal the coupled radiative, chemical, and dynamical processes that shape exoplanet atmospheres. Interpreting these atmospheres requires models that can capture this complexity.

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.

General circulation modelling of close-in extrasolar giant planets [PDF]

, 2011
PhDA large fraction of the extrasolar planets detected so far are giant planets that have such short orbital periods (a few days) that they are thought to be tidally-synchronised with the host star. Such orbits lead to permanent day/night sides on the

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.

KRONOS I: The 1–2.8 μm JWST Transmission Spectrum of the 23 Myr V1298 Tau c

The Astronomical Journal
While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window into understanding their primordial compositions.
