An improved model of the Edgeworth-Kuiper debris disk

Collisional Evolution of Edgeworth–Kuiper Belt Objects

theoretical evidence for a population of bodies beyond the region of the giant planets. Edgeworth (1949) and Kuiper The Edgeworth–Kuiper Belt contains a population of objects P10 times that of the main asteroid belt, spread over a volume (1951) argued for such a population based on the composiP10 larger and with relative speeds P10 times lower. As for tion of comets and the implausibility of a ...

Formation and Collisional Evolution of the Edgeworth-kuiper Belt

The color distribution in the Edgeworth-Kuiper Belt

We have started since 1997 the Meudon Multicolor Survey of Outer Solar System Objects with the aim of collecting a large and homogeneous set of color data for TransNeptunian and Centaurs objects. We present here our latest B-V, V-R and R-I colors measurements obtained with the CFH12K mosaic camera of the 3.6m Canada-FranceHawaii Telescope (CFHT). With the colors of 30 objects reported in this w...

The Kuiper Belt and Other Debris Disks

We discuss the current knowledge of the Solar system, focusing on bodies in the outer regions, on the information they provide concerning Solar system formation, and on the possible relationships that may exist between our system and the debris disks of other stars. Beyond the domains of the Terrestrial and giant planets, the comets in the Kuiper belt and the Oort cloud preserve some of our mos...

Collisional Erosion in the Primordial Edgeworth-kuiper Belt and the Generation of the 30è50 Au Kuiper Gap

One of the oustanding questions about the architecture of the outer solar system is how the transNeptunian disk of comets and small planet-scale objects known as the solar systemÏs Edgeworth-Kuiper Belt (EKB) originated and evolved to its present mass and architecture. Applying a time-dependent model of collisonal evolution of the EKB, we Ðnd that under a wide range of assumptions, collisional ...
