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…
KRONOS II: Solar-like Umbra and Penumbra Properties on the Young Sun V1298~Tau
Matthew M. Murphy, Adina D. Feinstein, Meir E. Schochet +14
Transiting exoplanets provide a unique laboratory for studying stellar surface heterogeneities via starspot or facular occultations. When observed at multiple wavelengths, this con…
The tale of the 3 planets: 3D cloud feedback enhances the spectral diversity of warm Jupiters
Nishil Mehta, Vivien Parmentier, Xianyu Tan +14
JWST has shown a large diversity in warm Jupiter spectra, despite only small variations in the planetary parameters. However, the main driver of this diversity remains unclear. We…
The Identification of CS2 and Evidence for Carbon-Sulfur Chemical Coupling in a Warm Giant Exoplanet Atmosphere
Anastasia Triantafillides, Thomas G. Beatty, Matthew C. Nixon +13
Transmission spectroscopy with the James Webb Space Telescope (JWST) is revealing growing chemical complexity in giant exoplanet atmospheres. Of particular interest is sulfur, whic…
Super-Solar Metallicity and Tentative Evidence for Photochemistry on WASP-96b from JWST and Ground-Based VLT Transmission Spectroscopy
Michael Radica, Jake Taylor, Yoav Rotman +13
With its expanded wavelength coverage and increased precision compared to previous space-based observatories, JWST provides the opportunity to revisit benchmark planets and view th…
Cloudy solutions for the clear skies of WASP-80b: 3D cloud feedback on the atmosphere and spectra of a warm Jupiter
Nishil Mehta, Vivien Parmentier, Xianyu Tan +14
Close-in warm Jupiters orbiting M dwarf stars are expected to exhibit diverse atmospheric chemistry, with clouds playing a key role in shaping their albedo, heat distribution, and…
