Self-Consistent Evolution Models Show Weak Double-Diffusive Mixing in Jupiter and Saturn

J. R. Fuentes, Ankan Sur, David J. Stevenson +1

Double-diffusive convection in the ``fuzzy'' cores of giant planets has been widely discussed as a mechanism for redistributing heavy elements, but its efficiency in evolutionary m…

Next-Generation Atmosphere Models for Giant Planets with Application to Coupled Interior Composition and Spectral Evolution I: Cloudless Models with Equilibrium Chemistry

Yi-Xian Chen, Roberto Tejada Arevalo, Adam Burrows +1

We present updated atmosphere models designed for calculating the post-formation evolution and cooling of giant planets with masses between and . Our tables provide…

Worlds Next Door. III. Indirect Evidence for Enhanced Atmospheric Metallicity and/or the Presence of Water Clouds in the Nearest Jupiter-analog Eri b

Aniket Sanghi, James Mang, Jorge Llop-Sayson +12

We present the most sensitive direct imaging search for the nearest ( pc) Jupiter-analog exoplanet, Eri b, with JWST/NIRCam coronagraphy between 4-5 m (F444W). We…

Next-Generation Improvements in Giant Exoplanet Evolutionary and Structural Models

Ankan Sur, Roberto Tejada Arevalo, Adam Burrows +1

Many evolutionary models of giant exoplanets still rely on simplifying assumptions that are no longer adequate given detailed constraints from Jupiter, Saturn, and modern exoplanet…
