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 +14
Transmission spectroscopy with the James Webb Space Telescope (JWST) is revealing growing chemical complexity in giant exoplanet atmospheres. Of particular interest is sulfur, whic…
GJ 523b is a Massive, 170 Myr-old Mega-Earth, Likely on a Polar Orbit
Maxwell A. Kroft, Thomas G. Beatty, Joseph M. Salzer +18
We use WIYN/NEID radial velocity measurements to confirm the planetary nature and measure the mass of the TESS transiting exoplanet candidate around the mid-K dwarf GJ 523 ($V=9.23…
A Panchromatic Characterization of the Evening and Morning Atmosphere of WASP-107 b: Composition and Cloud Variations, and Insight into the Effect of Stellar Contamination
Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +16
Limb-resolved transmission spectroscopy has the potential to transform our understanding of exoplanetary atmospheres. By separately measuring the transmission spectra of the evenin…
Out on a Limb: The Signatures of East-West Asymmetries in Transmission Spectra from General Circulation Models
Kenneth E. Arnold, Arjun B. Savel, Eliza M. -R. Kempton +5
In the era of JWST, observations of hot Jupiter atmospheres are becoming increasingly precise. As a result, the signature of limb asymmetries due to temperature or abundance differ…
