Thommes, Soko Matsumura, Frederic A. Rasio (Submitted on 11 Aug 2008) 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. http://arxiv.org/PS_cache/arxiv/pdf/0808/0808.1439v1.pdf Received on Tue 02 Sep 2008 10:47:05 AM PDT |
