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
TERRESTRIAL PLANET FORMATION FROM AN ANNULUS
It has been shown that some aspects of the terrestrial planets can be explained, particularly the Earth/Mars mass ratio, when they form from a truncated disk with an outer edge near 1.0 au (Hansen
A New Hybrid N-Body-Coagulation Code for the Formation of Gas Giant Planets
We describe an updated version of our hybrid N-body-coagulation code for planet formation. In addition to the features of our 2006-2008 code, our treatment now includes algorithms for the
Formation of Super-Earth Mass Planets at 125-250 AU from a Solar-type Star
We investigate pathways for the formation of icy super-Earth mass planets orbiting at 125-250 AU around a 1 solar mass star. An extensive suite of coagulation calculations demonstrates that swarms of
Terrestrial Rock Gas Planet Mass Gas Giant Ice Giant Ices
The standard planetesimal model of terrestrial-planet formation is based on astronomical and cosmochemical observations, and the results of laboratory experiments and numerical simulations. In this
Terrestrial Planet Formation: Dynamical Shake-up and the Low Mass of Mars
We consider a dynamical shake-up model to explain the low mass of Mars and the lack of planets in the asteroid belt. In our scenario, a secular resonance with Jupiter sweeps through the inner solar
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
Making Planet Nine: Pebble Accretion at 250--750 AU in a Gravitationally Unstable Ring
We investigate the formation of icy super-Earth mass planets within a gravitationally unstable ring of solids orbiting at 250-750 AU around a 1 solar mass star. Coagulation calculations demonstrate

Formation of Protoplanets from Planetesimals in the Solar Nebula
Planetary accretion from planetesimals to protoplanets is investigated using three-dimensional N-body simulations. The effect of gas drag due to solar nebula is included and realistic-sized
Formation of Protoplanet Systems and Diversity of Planetary Systems
We investigate the formation of protoplanet systems from planetesimal disks by global (N = 5000 and 10,000 and 0.5 AU 2. The growth timescale increases with a but decreases with Σ1. Based on the
Planet formation by coagulation: A focus on Uranus and Neptune
Planets form in the circumstellar disks of young stars. We review the basic physical processes by which solid bodies accrete each other and alter each others' random velocities, and we provide
The Growth of Planetary Embryos: Orderly, Runaway, or Oligarchic?
We consider the growth of a protoplanetary embryo embedded in a planetesimal disk. We take into account the dynamical evolution of the disk caused by (1) planetesimal-planetesimal interactions, which

Accretional Evolution of a Planetesimal Swarm
We use our multi-zone simulation code (D. Spaute, S. Weidenschilling, D. R. Davis, and F. Marzari,Icarus92,147–164, 1991) to model numerically the accretion of a swarm of planetesimals in the region

We investigate the growth and the orbital evolution of protoplanets embedded in a swarm of planetesimals using three-dimensionalN-body simulations. We find that among protoplanets, larger ones grow
