Scientific paper

The Canada-France Ecliptic Plane Survey (CFEPS) obtained characterized observations of 321 sq.deg. of sky to depths in the range g 23.5 - 24.4 AB mag, providing a database of 169 trans-neptunian objects (TNOs) with high-precision dynamical classification and known discovery efficiency. Using this database, we find that the main classical belt (a=40-47 AU) needs to be modeled with at least three components: the 'hot' component with a wide inclination distribution and two 'cold' components (stirred and kernel) with much narrower inclination distributions. The existence of the kernel poses strong constraint on models of the early solar system. We will present a sequence of events that can lead to the presence of the observed dynamical structure.
