A Clearer View of HAT-P-1 b: JWST NIRSpec G395H Reveals Water, Carbon Dioxide, and Possibly Hydrogen Sulfide

Reza Ashtari, Stephen P. Schmidt, Guangwei Fu +16

As part of JWST's Exoplanet Grand Tour Survey, we use panchromatic transmission spectroscopy to connect HAT-P-1 b's previously studied optical and near-infrared atmosphere to the l…

JWST color sequence of transiting exoplanets and directly imaged substellar objects

Guangwei Fu, Joshua D. Lothringer, Sagnick Mukherjee +4

Color-magnitude diagrams (CMDs) have been foundational across astrophysics, from galaxies and stars to brown dwarfs, and JWST now extends them to transiting exoplanets and self-lum…

Asymmetric Aerosol Distribution on the Terminators of the Warm Saturn WASP-69 b Revealed by JWST NIRISS/SOSS

Le-Chris Wang, Sagnick Mukherjee, Stephen P. Schmidt +16

How aerosols form, are transported, and cycle between condensation and evaporation across exoplanet temperature regimes remains poorly understood. Recent models and observations su…

No Helium Detected in LHS 1140 b from Four JWST NIRISS/SOSS Transits

Katherine A. Bennett, Carlos Gascón, Jacob Lustig-Yaeger +13

In the effort to determine which low-mass exoplanets have atmospheres, LHS 1140 b remains one of the most favorable targets. Its large size (5.6 and 1.7 $\rm R_{\o…

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…

Atmospheric asymmetries in WASP-121 b revealed by rotational transits detected with JWST

Cyril Gapp, Aurélien Falco, Thomas M. Evans-Soma +6

Close-in exoplanets are tidally locked to their host star and thus exhibit extreme atmospheric temperature gradients. It has been theorized that the fraction of star light absorbed…
