Formation and Evolution Simulations of Saturn, Including Composition Gradients and Helium Immiscibility
Peter Bodenheimer, David J. Stevenson, Jack J. Lissauer +1
The formation of Saturn is modeled by detailed numerical simulations according to the core-nucleated accretion scenario. Previous models are enhanced to include the dissolution of…
