@article{Bromley2006TERRESTRIALPF, title={TERRESTRIAL PLANET FORMATION. I. THE TRANSITION FROM OLIGARCHIC GROWTH TO CHAOTIC GROWTH}, author={S. J. Bromley}, journal={The Astronomical Journal}, year={2006}, volume={131}, pages={1837-1850} }
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 the mass in planetesimals and (2) the surface density in oligarchs exceeds 2-3 g cm-2 at 1 AU, strong dynamical interactions among oligarchs produce a high merger rate, which…

We investigate planetesimal accretion via a direct N-body simulation of an annulus at 1 au orbiting a 1 M$\odot$ star. The planetesimal ring, which initially contains N = 106 bodies is evolved into…

On the Formation of Planetesimals Via Secular Gravitational Instabilities with Turbulent Stirring

We study the gravitational instability (GI) of small solids in a gas disk as a mechanism to form planetesimals. Dissipation from gas drag introduces secular GI, which proceeds even when standard GI…
