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…
Sub-Neptune Memories I: Implications of Inefficient Mantle Cooling and Silicate Rain
Roberto Tejada Arevalo, Akash Gupta, Adam Burrows +3
We explore the evolution of sub-Neptune (radii between 1.5 and 4 R) exoplanet interior structures using our upgraded evolution code, \texttt{APPLE}, which self-consi…
The Fate of Hydrogen and Helium: From Planetary Embryos to Earth- and Neptune-like Worlds
Akash Gupta, Haiyang Luo, Jie Deng +1
Hydrogen, helium, silicates, and iron are key building blocks of rocky and gas-rich planets, yet their chemical interactions remain poorly constrained. Using first-principles molec…
