Biological, Equilibrium and Photochemical Signatures of C, N and S Isotopes in the Early Earth and Exoplanet Atmospheres [PDF]
LifeThe unambiguous detection of biosignatures in exoplanet atmospheres is a primary objective for astrobiologists and exoplanet astronomers. The primary methodology is the observation of combinations of gases considered unlikely to coexist in an atmosphere ...

High Accuracy Molecular Line Lists for Studies of Exoplanets and Other Hot Atmospheres [PDF]
Frontiers in Astronomy and Space Sciences, 2022 The desire to characterize and model the atmospheres of the many extrasolar planets that have been discovered over the last three decades is a major driver of current astronomy.

Can Isotopologues Be Used as Biosignature Gases in Exoplanet Atmospheres? [PDF]
Life, 2023 Isotopologue ratios are anticipated to be one of the most promising signs of life that can be observed remotely. On Earth, carbon isotopes have been used for decades as evidence of modern and early metabolic processes. In fact, carbon isotopes may be the

Spectra as windows into exoplanet atmospheres. [PDF]
Proc Natl Acad Sci U S A, 2014 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.

Annual Review of Astronomy and Astrophysics, 2010 At the dawn of the first discovery of exoplanets orbiting Sun-like stars in the mid-1990s, few believed that observations of exoplanet atmospheres would ever be possible. After the 2002 Hubble Space Telescope detection of a transiting exoplanet atmosphere, many skeptics discounted it as a one-object, one-method success.

Aerosols in Exoplanet Atmospheres [PDF]
Journal of Geophysical Research: Planets, 2021 AbstractObservations of exoplanet atmospheres have shown that aerosols, like in the solar system, are common across a variety of temperatures and planet types. The formation and distribution of these aerosols are inextricably intertwined with the composition and thermal structure of the atmosphere.

Simulations of idealised 3D atmospheric flows on terrestrial planets using LFRic-Atmosphere [PDF]
Geoscientific Model Development, 2023 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.
