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…

Sulfur Enrichment in Close-in Exoplanet Atmospheres Induced by Pebble Drift across the Salt Line

Kanon Nakazawa, Kazumasa Ohno

Observations of JWST have revealed that several close-in exoplanets have sulfur-rich atmospheres through SO detections. Atmospheric sulfur is often thought to originate from so…

A Dichotomy of the Mass-Metallicity Relation of Exoplanetary Atmospheres Demarcated by their Birthplace

Kazumasa Ohno, Masahiro Ikoma, Satoshi Okuzumi +1

Atmospheric observations by JWST raise a growing evidence that atmospheric metallicity exhibits an anti-correlation with masses of giant exoplanets. While such a trend was anticipa…
