Aerosols in Exoplanet Atmospheres [PDF]

Journal of Geophysical Research: Planets, 2021
Observations 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

Observations of Exoplanet Atmospheres [PDF]

Publications of the Astronomical Society of the Pacific, 2015
Detailed characterization of an extrasolar planet's atmosphere provides the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between initial composition, chemistry, dynamics & circulation, and

Phosphine as a Biosignature Gas in Exoplanet Atmospheres [PDF]

Astrobiology, 2019
A long-term goal of exoplanet studies is the identification and detection of biosignature gases. Beyond the most discussed biosignature gas O2, only a handful of gases have been considered in detail. In this study, we evaluate phosphine (PH3).

Aggregate Hazes in Exoplanet Atmospheres [PDF]

The Astrophysical Journal, 2019
Photochemical hazes have been frequently used to interpret exoplanet transmission spectra that show an upward slope towards shorter wavelengths and weak molecular features.

Radiative Transfer for Exoplanet Atmospheres [PDF]

, 2017
Remote sensing of the atmospheres of distant worlds motivates a firm understanding of radiative transfer. In this review, we provide a pedagogical cookbook that describes the principal ingredients needed to perform a radiative transfer calculation and ...

Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) [PDF]

Astronomy & Astrophysics, 2020
Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres.

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.

Optical properties of organic haze analogues in water-rich exoplanet atmospheres observable with JWST [PDF]

Nature Astronomy, 2023
JWST has begun its scientific mission, which includes the atmospheric characterization of transiting exoplanets. Some of the first exoplanets to be observed by JWST have equilibrium temperatures below 1000 K, which is a regime where photochemical hazes ...
