Five Key Exoplanet Questions Answered via the Analysis of 25 Hot-Jupiter Atmospheres in Eclipse [PDF]
Astrophysical Journal Supplement Series, 2022 Population studies of exoplanets are key to unlocking their statistical properties. So far, the inferred properties have been mostly limited to planetary, orbital, and stellar parameters extracted from, e.g., Kepler, radial velocity, and Gaia data.

The Sensitivity of Eclipse Mapping to Planetary Rotation
The Astronomical Journal, 2022 Mapping exoplanets across phases and during secondary eclipse is a powerful technique for characterizing Hot Jupiters in emission. Since these planets are expected to rotate about axes normal to their orbital planes, with rotation periods synchronized ...

A New Method for Studying Exoplanet Atmospheres Using Planetary Infrared Excess [PDF]
Astrophysical Journal, 2020 To date, the ability for observers to reveal the composition or thermal structure of an exoplanet’s atmosphere has rested on two techniques: high-contrast direct imaging and time-series observations of transiting exoplanets.

A Catalog of Exoplanet Atmospheric Retrieval Codes
Research Notes of the AAS, 2023 Abstract Exoplanet atmospheric retrieval is a computational technique widely used to infer properties of planetary atmospheres from remote spectroscopic observations. Retrieval codes typically employ Bayesian sampling algorithms or machine learning approaches to explore the range of atmospheric properties (e.g., chemical composition ...

The Detectability and Characterization of the TRAPPIST-1 Exoplanet Atmospheres with JWST [PDF]
Astronomical Journal, 2019 The James Webb Space Telescope (JWST) will offer the first opportunity to characterize terrestrial exoplanets with sufficient precision to identify high mean molecular weight atmospheres, and TRAPPIST-1's seven known transiting Earth-sized planets are ...

Laboratory studies on the viability of life in H2-dominated exoplanet atmospheres [PDF]
Nature Astronomy, 2020 Theory and observation for the search for life on exoplanets via atmospheric ‘biosignature gases’ is accelerating, motivated by the capabilities of the next generation of space- and ground-based telescopes.

The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars [PDF]
, 2012 The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M ...
