Inhomogeneous Cloud Coverage and Altitude-Dependent Heat Transport on the Hot-Jupiter NGTS-10 Ab from its Optical-to-Infrared Phase Curve

Louis-Philippe Coulombe, Vivien Parmentier, Kevin B. Stevenson +15

Hot-Jupiters, gas giant planets with equilibrium temperatures above 1,000 K, host large temperature gradients between their permanent day- and nightsides, resulting in circulation…

C, N, O, S, and photochemistry in a temperate giant planet orbiting a late M dwarf

Michael Zhang, Qiao Xue, Jeehyun Yang +20

We report the JWST NIRSpec/PRISM transit spectrum of TOI-6894b, an exceptional 420 K sub-Saturn that is one of the rare giant planets transiting a late M dwarf. Remarkably, both th…

Magnetic field strengths of hot giant exoplanets consistent with Solar System values

Julia V. Seidel, Vivien Parmentier, Bibiana Prinoth +29

Magnetic fields are ubiquitous in the universe. They play a key role in shaping the activity of stars, the habitability of rocky planets, and the long-term retention of planetary a…

Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres

Jeehyun Yang, Vighnesh Nagpal, Michael Zhang +16

Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in…

Horizontal and vertical exoplanet thermal structure from a JWST spectroscopic eclipse map

Ryan C. Challener, Megan Weiner Mansfield, Patricio E. Cubillos +33

Highly-irradiated giant exoplanets known as "ultra-hot Jupiters" are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, la…

Detection of carbon monoxide's 4.6 micron fundamental band structure in WASP-39b's atmosphere with JWST NIRSpec G395H

David Grant, Joshua D. Lothringer, Hannah R. Wakeford +28

Carbon monoxide (CO) is predicted to be the dominant carbon-bearing molecule in giant planet atmospheres, and, along with water, is important for discerning the oxygen and therefor…

Updated Planetary Mass Constraints of the Young V1298 Tau System Using MAROON-X

James Sikora, Jason Rowe, Saugata Barat +14

The early K-type T-Tauri star, V1298 Tau (, ) hosts four transiting planets with radii ranging from . The thre…

A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b

Louis-Philippe Coulombe, Björn Benneke, Ryan Challener +73

Close-in giant exoplanets with temperatures greater than 2,000 K (''ultra-hot Jupiters'') have been the subject of extensive efforts to determine their atmospheric properties using…

Early Release Science of the Exoplanet WASP-39b with JWST NIRSpec G395H

Lili Alderson, Hannah R. Wakeford, Munazza K. Alam +89

Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a crucial avenue for unlocking the formation and evolution of exoplanetary systems. Access to a…
