2 00 8 The Warped Plane of the Classical Kuiper Belt
By numerically integrating the orbits of the giant planets and of test particles for four billion years, we follow the evolution of the location of the midplane of the Kuiper belt. The Classical Kuiper belt conforms to a warped sheet that precesses with a 1.9 Myr period. The present-day location of the Kuiper belt plane can be computed using linear secular perturbation theory: the local normal ...
متن کاملThe Radial Distribution of the Kuiper Belt
We examine the radial distribution of the Kuiper Belt objects (KBOs) using a method that is insensitive to observational bias effects. This technique allows the use of the discovery distances of all KBOs, independent of orbital classification or discovery circumstance. We verify the presence of an outer edge to the Kuiper Belt, as reported in other works, and we measure this edge to be at given...
متن کاملThe Small Numbers of Large Kuiper Belt Objects
We explore the brightness distribution of the largest and brightest (m(R)<22) Kuiper belt objects (KBOs). We construct a luminosity function of the dynamically excited or hot Kuiper belt (orbits with inclinations > 5) from the very brightest to m(R)=23. We find for m(R). 23, a single slope appears to describe the luminosity function. We estimate ∼12 KBOs brighter than m(R)∼19.5 are present in t...
متن کاملThe Dynamical Structure of the Kuiper Belt and Its Primordial Origin
Since its discovery in 1992, the Kuiper belt has slowly revealed a stunningly complex dynamical structure. This structure has been a gold mine for those of us interested in planet formation because it provides vital clues about this process. This chapter is a review of the current state of knowledge about these issues. It is divided in two parts. The first part (section 2) is devoted to the des...
متن کاملSecular Resonance Sweeping in a Self–gravitating Planetesimal Disk, with Application to the Kuiper Belt
One of the more puzzling aspects of the Kuiper Belt is the high orbital inclinations exhibited by Kuiper Belt Objects (KBOs). This swarm of distant comets have apparent inclinations of ∼ 15◦ that to date have defied all simple explanations. Several distinct models have been offered as explanations for the Kuiper Belt’s dynamical excitation: gravitational stirring by protoplanets that may have o...

By numerically integrating the orbits of the giant planets and of test particles over a period of four billion years, we follow the evolution of the location of the midplane of the Kuiper belt. The Classical Kuiper belt conforms to a warped sheet that precesses with a 1.9 Myr period.
