Recovering the Morning and Evening Limbs of WASP-94Ab from Its Limb-Averaged JWST Transmission Spectrum

Tyler R. Fairnington, Michael Radica, Michael Zhang +5

Recent JWST observations have revealed that the morning and evening limbs of the hot Jupiter WASP-94Ab have very different transmission spectra. An analysis of these resolved limb…

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…

JWST MIRI reveals a potential atmosphere on the ultra-hot rocky planet TOI-431b

Cole Smith, Brandon Park Coy, Megan Weiner Mansfield +13

An open question in exoplanet science is whether rocky exoplanets extremely close in to their host stars, `lava worlds', can retain significant atmospheres. Thermal emission observ…

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…

The Roasting Marshmallows Program with IGRINS on Gemini South V: Atmosphere of MASCARA-1b is Enriched in Refractory Elements

Krishna Kanumalla, Michael R. Line, Martina Chiarella +75

Ultra-hot Jupiters (UHJs; K) enable simultaneous detection of volatile (ice-forming) and refractory (rock-forming) species in planetary atmospheres, provi…

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 transport as a source of disequilibrium chemistry on the nightside of a hot exoplanet

Vivien Parmentier, Kevin B. Stevenson, Luis Welbanks +15

Hot Jupiters have temperature gradients of several hundreds of degrees between their permanent day and nightsides. In equilibrium, the primary carbon reservoir is expected to trans…

Evidence for an Atmosphere on the Ultra-Short Period super-Earth HD 3167 b

Brandon Park Coy, Qiao Xue, Megan Weiner Mansfield +14

'Lava worlds'-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characteriza…

The MUSCLES Extension for Atmospheric Transmission Spectroscopy: Spectral energy distributions for 20 exoplanet host stars that JWST observed in Cycle 1

David J. Wilson, Allison Youngblood, Girish M. Duvvuri +11

Correctly interpreting JWST spectra of close-in exoplanets requires a measurement of the X-ray and ultraviolet light that the planets receive from their host stars. Here we provide…
