Abstract

The initial conditions, physics, and outcome of planet formation are now constrained by detailed observations of protoplanetary disks, laboratory experiments, and the discovery of thousands of extrasolar planetary systems. These developments have broadened the range of processes that are considered important in planet formation, to include disk turbulence, radial drift, planet migration, and pervasive post-formation dynamical evolution. The N-body collisional growth of planetesimals and protoplanets, and the physics of planetary envelopes - key ingredients of the classical model - remain central. I provide an overview of the current status of planet formation theory, and discuss how it connects to observations.
