A JWST transiting survey of FGK stellar limb darkening: empirical evidence for quadratic laws and atmospheric model comparisons

David K. Sing, Joshua D. Lothringer, Jeff A. Valenti +11

We present a study of stellar limb-darkening using JWST transit observations of seven exoplanets orbiting FGK host stars, spanning 4200-6800 K. The wide wavelength coverage and hig…

Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab

Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33

Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…

A parameterised approach to disequilibrium retrievals in the JWST era: Application to NIRCam observations of HD 189733b

Jake Taylor, Shang-Min Tsai, Vivien Parmentier +2

Atmospheric retrievals are a widely used technique for inferring the physical and chemical properties of exoplanetary atmospheres from observed spectra. A common simplifying assump…

KRONOS I: The m JWST Transmission Spectrum of the 23 Myr V1298 Tau c

Matthew M. Murphy, Matthew C. Nixon, Adina D. Feinstein +16

While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window i…

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…
