Ultraviolet Radiation Effects on the Optical Properties of Water-Dominated Exoplanet Hazes
Lori Huseby, Sarah E. Moran, Tiffany Kataria +8
Temperate sub-Neptune and terrestrial exoplanets could contain large inventories of water in various phases, such as water-dominated atmospheres or even oceans. Observations have s…
Characterizing Transiting Exoplanet Atmospheres in the 2030s with the Hubble Space Telescope
Joshua D. Lothringer, Hannah R. Wakeford, Robert C. Frazier +7
The Hubble Space Telescope inaugurated the era of exoplanet atmospheric characterization. While the James Webb Space Telescope has largely taken up the mantle of infrared atmospher…
Open Source High-Resolution Exoplanet Atmosphere Retrievals with POSEIDON
Ruizhe Wang, Ryan J. MacDonald, Neale P. Gibson +1
High-resolution spectroscopy (R > 25,000) has opened new opportunities to characterize exoplanet atmospheres from the ground. By resolving individual lines in planetary emission an…
Implementation of Aerosol Mie Scattering in POSEIDON with Application to the hot Jupiter HD 189733 b's Transmission, Emission, and Reflected Light Spectrum
Elijah Mullens, Nikole K. Lewis, Ryan J. MacDonald
Aerosols are a ubiquitous feature of planetary atmospheres and leave clear spectral imprints in exoplanet spectra. Pre-JWST, exoplanet retrieval frameworks mostly adopted simple pa…
