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…
ORCHARD: A General Planetary Evolution Code
Roberto Tejada Arevalo, Adam Burrows, Ankan Sur +1
We present \texttt{ORCHARD}, a publicly available planetary evolution code based on the gas giant evolution code, \texttt{APPLE}, capable of modeling the evolution and structures o…
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 a…
Saturn's Evolutionary History and Seismology: Survival of Deep Stably Stratified Regions in Evolutionary Models of Saturn Consistent with Ring Seismology
Yubo Su, Janosz W. Dewberry, Roberto Tejada Arevalo +2
With recent advances in the modeling of the solar system giant planets, rapid progress has been made in understanding the remaining questions pertaining to their formation and evol…
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…
An Energy Perspective of Core Erosion in Gas Giant Planets
J. R. Fuentes, Christopher R. Mankovich, Ankan Sur
Juno and Cassini have shown that Jupiter and Saturn likely contain extended gradients of heavy elements. Yet, how these gradients can survive over billions of years remains an open…
The Evolution of Jupiter and Saturn as a function of the Parameter R
Ankan Sur, Adam Burrows, Roberto Tejada Arevalo +1
Computed using the APPLE planetary evolution code, we present updated evolutionary models for Jupiter and Saturn that incorporate helium rain, non-adiabatic thermal structures, and…
Simultaneous Evolutionary Fits for Jupiter and Saturn Incorporating Fuzzy Cores
Ankan Sur, Roberto Tejada Arevalo, Yubo Su +1
With the recent realization that there likely are stably-stratified regions in the interiors of both Jupiter and Saturn, we construct new non-adiabatic, inhomogeneous evolutionary…
Jupiter Evolutionary Models Incorporating Stably Stratified Regions
Roberto Tejada Arevalo, Ankan Sur, Yubo Su +1
We address the issue of which broad set of initial conditions for the planet Jupiter best matches the current presence of a ``fuzzy core" of heavy elements, while at the same time…
APPLE: An Evolution Code for Modeling Giant Planets
Ankan Sur, Yubo Su, Roberto Tejada Arevalo +2
We introduce APPLE, a novel planetary evolution code designed specifically for the study of giant exoplanet and Jovian planet evolution in the era of Galileo, Juno, and Cassini. Wi…
Equations of State, Thermodynamics, and Miscibility Curves for Jovian Planet and Giant Exoplanet Evolutionary Models
Roberto Tejada Arevalo, Yubo Su, Ankan Sur +1
The equation of state of hydrogen-helium (H-He) mixtures plays a vital role in the evolution and structure of gas giant planets and exoplanets. Recent equations of state that accou…
Jupiter Atmospheric Models and Outer Boundary Conditions for Giant Planet Evolutionary Calculations
Yi-Xian Chen, Adam Burrows, Ankan Sur +1
We present updated atmospheric tables suitable for calculating the post-formation evolution and cooling of Jupiter and Jupiter-like exoplanets. These tables are generated using a 1…
