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…
