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…

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…

Atmospheric Circulation of High-Obliquity Mini-Neptunes

Yanhong Lai, Xianyu Tan, Yubo Su

With the operation of JWST, atmospheric characterization has now extended to low-mass exoplanets. In compact multiplanetary systems, secular spin-orbital resonance may preserve hig…

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…

The Coupled Tidal Evolution of the Moons and Spins of Warm Exoplanets

Yubo Su, Melaine Saillenfest

Context: The Solar System giant planets harbour a wide variety of moons. Moons around exoplanets are plausibly similarly abundant, even though most of them are likely too small to…

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…
