The Open-source Photochem Code: A General Chemical and Climate Model for Interpreting (Exo)Planet Observations

The Planetary Science Journal
With the launch of the James Webb Space Telescope, we are firmly in the era of exoplanet atmosphere characterization. Understanding exoplanet spectra requires atmospheric simulations that span the diversity of planetary atmospheres.

Modeling Clouds in Brown Dwarf and Exoplanet Giant Planet Atmospheres [PDF]

, 2018
Clouds and hazes are commonplace in the atmospheres of solar system planets and are likely ubiquitous in the atmospheres of extrasolar planets as well. Clouds affect every aspect of a planetary atmosphere, from the transport of radiation, to atmospheric ...

JWST-TST DREAMS: Nonuniform Dayside Emission for WASP-17b from MIRI/LRS

The Astronomical Journal
We present the first spectroscopic characterization of the dayside atmosphere of WASP-17b in the mid-infrared using a single JWST MIRI/LRS eclipse observation.

HST Transmission Spectra of the Hot Neptune HD 219666 b: Detection of Water and the Challenge of Constraining Both Water and Methane

The Astronomical Journal
Although Neptunian-sized (2–5 R _⊕ ) planets appear to be extremely common in the Galaxy, many mysteries remain about their overall nature. To date, only 11 Neptunian-sized planets have had their atmospheres spectroscopically characterized, and these ...

Uniform Reanalysis of JWST MIRI 15 μm Exoplanet Eclipse Observations Using Frame-normalized Principal Component Analysis

The Astrophysical Journal Letters
James Webb Space Telescope (JWST) MIRI 15 μ m time-series eclipse photometry presents a powerful way to probe for the presence of atmospheres on low-temperature rocky exoplanets orbiting nearby stars.

Exoplanet atmospheres at high spectral resolution

The spectrum of an exoplanet reveals the physical, chemical, and biological processes that have shaped its history and govern its future. However, observations of exoplanet spectra are complicated by the overwhelming glare of their host stars.

High-contrast spectroscopy of exoplanet atmospheres [PDF]

More than 5,000 exoplanets have been found over the past couple of decades. These exoplanets show a tremendous diversity, ranging from scorching hot Jupiters, common super-Earths, to widely separated super-Jupiters on the planet/brown dwarf boundary.
