The SPACE Program II: No discernible spectral features in the transmission spectrum of the sub-Neptune HD 191939 b observed with HST/WFC3
Cyril Gapp, Lorena Acuña-Aguirre, Reza Ashtari +17
The atmospheres of sub-Neptunes provide a window into their internal structure and history, shedding light on the origin of this common, but enigmatic, class of exoplanets. However…
Retrieving the Red Edge on Earth-like Planets with Heterogeneous Clouds and Surfaces
Zachary Burr, Mario Damiano, Vincent Kofman +2
The detection and characterization of potentially habitable exoplanets is one of the chief goals of astrophysics for the coming decades. Imaging in reflected light is well suited f…
Direct imaging characterization of cool gaseous planets
Michiel Min, Jo Barstow, Laura C. Mayorga +19
Cool gas giant exoplanets, particularly those with properties similar to those of Jupiter and Saturn, remain poorly characterized due to current observational limitations. This whi…
Volcanic Satellites Tidally Venting Na, K, SO2 in Optical & Infrared Light
Apurva V. Oza, Andrea Gebek, Moritz Meyer zu Westram +19
Recent infrared spectroscopy from the James Webb Space Telescope (JWST) has spurred analyses of common volcanic gases such as carbon dioxide (CO2), sulfur dioxide (SO2), alongside…
A water-rich interior in the temperate sub-Neptune K2-18 b revealed by JWST
Renyu Hu, Aaron Bello-Arufe, Armen Tokadjian +7
Temperate sub-Neptunes are compelling targets for detecting liquid-water oceans beyond the Solar System. If water-rich and lacking massive hydrogen-helium envelopes, these planets…
Effects of planetary mass uncertainties on the interpretation of the reflectance spectra of Earth-like exoplanets
Mario Damiano, Zachary Burr, Renyu Hu +2
Atmospheric characterization of Earth-like exoplanets through reflected light spectroscopy is a key goal for upcoming direct imaging missions. A critical challenge in this endeavor…
