Terrestrial Planet Formation. I. The Transition from Oligarchic Growth to Chaotic Growth
Terrestrial Planet Formation. I. The Transition from Oligarchic Growth to Chaotic Growth
We use a hybrid, multiannulus, n-body-coagulation code to investigate the growth of kilometer-sized planetesimals at 0.4-2 AU around a solar-type star. After a short runaway growth phase, protoplanets with masses of ∼1026 g and larger form throughout the grid. When (1) the mass in these "oligarchs" is roughly comparable to …
