A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion
Jerry W. Xuan, William O. Balmer, Yayaati Chachan +25
AF Lep b is one of the closest analogs to Jupiter in terms of mass () and semi-major axis ( AU) amenable to spectroscopic characterization. We present JWST/NIR…
Heavy element enrichment of gas in surface-accretion disks: A possible origin of the mass-metallicity anti-correlation in exoplanets
Yoshitaka Ikeda, Kazumasa Ohno, Satoshi Okuzumi
Recent observations, including those by JWST, suggest that the atmospheres of many gas giant exoplanets have super-stellar metallicity that is anti-correlated with planetary mass.…
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…
Beyond monoculture: Polydisperse moment methods for sub-stellar atmosphere cloud microphysics II. A three-moment gamma distribution formulation for GCM applications
Elspeth K. H. Lee, Kazumasa Ohno
Context. Understanding how the shape of cloud particle size distributions affects the atmospheric properties of sub-stellar atmospheres is a key area to explore, particularly in th…
Revising the Giant Planet Mass-Metallicity Relation: Deciphering the Formation Sequence of Giant Planets
Yayaati Chachan, Jonathan J. Fortney, Kazumasa Ohno +2
The rate at which giant planets accumulate solids and gas is a critical component of planet formation models, yet it is extremely challenging to predict from first principles. Char…
Fractal Aggregate Aerosols in the Virga Cloud Code I: Model Description and Application to a Benchmark Cloudy Exoplanet
Sarah E. Moran, Matt G. Lodge, Natasha E. Batalha +5
We introduce new functionality to treat fractal aggregate aerosol particles within the Virga cloud modeling framework. Previously, the open source cloud modeling code Virga (Batalh…
