Dynamics of Discs and Planets

The detected explanted systems show orbital characteristic quite different to our solar systems. While planets in solar systems are in near-circular orbits and have a moderate distance to the sun, lots of exoplanets locate either in close-in orbits, or in eccentric orbits. To understanding the underlying factors, we performed N-body simulation on the late stage planet formation. Some major signatures of the observed eoxplanets are reproduced, especially the eccentricity-semimajor relation. We also find that the depletion timescale of protoplanetary disk makes the difference between the solar system and exoplanet systems. A planetary category is proposed according to this effect.
