Mitigating Charge Migration in JWST NIRISS Reveals That KELT-7 b is a Metal-enriched Ultra-hot Jupiter Orbiting a Young Metal-rich Star
Stephen P. Schmidt, Erin M. May, Joshua D. Lothringer +19
We present the first panchromatic JWST transmission spectrum of an ultra-hot Jupiter, combining NIRISS and NIRSpec observations to constrain KELT-7\,b's atmospheric properties. We…
Cloudy mornings and clear evenings on a gas giant exoplanet
Sagnick Mukherjee, David K. Sing, Guangwei Fu +25
The spectra of exoplanet atmospheres are affected by aerosols (clouds and hazes) of uncertain origin. Proposed aerosol formation mechanisms include gas condensation or photochemica…
A Comprehensive Reanalysis of K2-18 b's JWST NIRISS+NIRSpec Transmission Spectrum
Stephen P. Schmidt, Ryan J. MacDonald, Shang-Min Tsai +13
Sub-Neptunes are the most common type of planet in our galaxy. Interior structure models suggest that the coldest sub-Neptunes could host liquid water oceans underneath their hydro…
Overcast mornings and clear evenings in hot Jupiter exoplanet atmospheres
Guangwei Fu, Sagnick Mukherjee, Kevin B. Stevenson +10
Aerosols is an old topic in the young field of exoplanet atmospheres. Understanding what they are, how they form, and where they go has long provided a fertile playground for theor…
A Revised Density Estimate for the Largest Known Exoplanet, HAT-P-67 b
Gavin Wang, William O. Balmer, Laurent Pueyo +7
Low-density () hot Saturns are expected to quickly ( Myr) lose their atmospheres due to stellar irradiation, explaining their rarity. HAT-P-67 b seem…
