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…

Planet Formation by Gas-Assisted Accretion of Small Solids
Gennaro D'Angelo, Peter Bodenheimer
We compute the accretion efficiency of small solids, with radii 1 cm Rs 10 m, on planets embedded in gaseous disks. Planets have masses 3 Mp 20 Earth masses…
