Understanding Exoplanet Atmospheres with UV Observations II: The Far UV and Atmospheric Escape [PDF]
arXiv, 2019 Much of the focus of exoplanet atmosphere analysis in the coming decade will be at infrared wavelengths, with the planned launches of the James Webb Space Telescope (JWST) and the Wide-Field Infrared Survey Telescope (WFIRST). However, without being placed in the context of broader wavelength coverage, especially in the optical and ultraviolet ...

True Polar Wander of Lava Worlds
The Astrophysical Journal Letters, 2023 As one of the most detectable types of terrestrial planets, lava worlds are highly prioritized targets for exoplanet atmosphere characterization since their atmospheres may reveal what they are made of and how.

Atmospheric Escape and the Evolution of Close-In Exoplanets [PDF]
Annual Review of Earth and Planetary Sciences, 2019 Exoplanets with substantial hydrogen/helium atmospheres have been discovered in abundance, many residing extremely close to their parent stars. The extreme irradiation levels that these atmospheres experience cause them to undergo hydrodynamic atmospheric escape.

Gas Phase Chemistry of Cool Exoplanet Atmospheres: Insight from Laboratory Simulations [PDF]
ACS Earth and Space Chemistry, 2018 Photochemistry induced by stellar UV flux should produce haze particles in exoplanet atmospheres. Recent observations indicate that haze and/or cloud layers exist in the atmospheres of exoplanets.

Exoplanet Atmospheres with JWST
, 2022 Planetary atmospheres are diverse. They hold key insights into the complex physics and chemistry that has shaped them through formation. In this talk I focus on the understanding we have gained on exoplanet atmospheres from transiting studies, including the importance of wide wavelength coverage.

Limits on Clouds and Hazes for the TRAPPIST-1 Planets
, 2018 The TRAPPIST-1 planetary system is an excellent candidate for study of the evolution and habitability of M-dwarf planets. Transmission spectroscopy observations performed with the Hubble Space Telescope (HST) suggest the innermost five planets do not ...
