We present new optical transmission spectra for two hot Jupiters: WASP-25b (M = 0.56~M; R = 1.23 R; P =~3.76 days) and WASP-124b (M = 0.58~M; R = 1.34 R; P = 3.37 d…
High Tide or Riptide on the Cosmic Shoreline? A Water-Rich Atmosphere or Stellar Contamination for the Warm Super-Earth GJ~486b from JWST Observations
Sarah E. Moran, Kevin B. Stevenson, David K. Sing +21
Planets orbiting M-dwarf stars are prime targets in the search for rocky exoplanet atmospheres. The small size of M dwarfs renders their planets exceptional targets for transmissio…
A JWST transmission spectrum of a nearby Earth-sized exoplanet

The critical first step in the search for life on exoplanets over the next decade is to determine whether rocky planets transiting small M-dwarf stars possess atmospheres and, if s…
GCM Constraints on the Detectability of the CO-CH Biosignature Pair on TRAPPIST-1e with JWST
Yoav Rotman, Thaddeus D. Komacek, Geronimo L. Villanueva +2
Terrestrial exoplanets such as TRAPPIST-1e will be observed in a new capacity with JWST/NIRSpec, which is expected to be able to detect CO, CH, and O signals, if presen…
The effect of interior heat flux on the atmospheric circulation of hot and ultra-hot Jupiters
Thaddeus D. Komacek, Peter Gao, Daniel P. Thorngren +2
Many hot and ultra-hot Jupiters have inflated radii, implying that their interiors retain significant entropy from formation. These hot interiors lead to an enhanced internal heat…
Early Release Science of the exoplanet WASP-39b with JWST NIRISS
Adina D. Feinstein, Michael Radica, Luis Welbanks +86
Transmission spectroscopy provides insight into the atmospheric properties and consequently the formation history, physics, and chemistry of transiting exoplanets. However, obtaini…
Early Release Science of the exoplanet WASP-39b with JWST NIRCam
Eva-Maria Ahrer, Kevin B. Stevenson, Megan Mansfield +96
Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a fundamental step towards constraining the dominant chemical processes at work and, if in eq…
Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM
