Gas disks to gas giants: Simulating the birth of planetary systems

    Abstract: The ensemble of now more than 250 discovered planetary systems
displays a wide range of masses, orbits and, in multiple systems, dynamical
interactions. These represent the end point of a complex sequence of events,
wherein an entire protostellar disk converts itself into a small number of
planetary bodies. Here, we present self-consistent numerical simulations of this
process, which produce results in agreement with some of the key trends observed
in the properties of the exoplanets. Analogs to our own solar system do not
appear to be common, originating from disks near the boundary between barren and
(giant) planet-forming.
