Ex(o)plain: Subgroup-Level Analysis of Exoplanet Atmospheric Parameters

IEEE Access
Deep learning has been shown to be a valuable tool in astrophysics. In the field of exoplanetary science, deep learning-based approaches are being used extensively to automate the characterization of exoplanet atmospheres, reducing computational costs ...

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 ...

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.
