We numerically integrated the orbits of 1458 particles in the region of the classical Kuiper belt (41 AU ≤ a ≤ 47 AU) to explore the role of dynamical instabilities in sculpting the inclination distribution of the classical Kuiper belt objects (KBOs). We find that the selective removal of low-inclination objects by overlapping secular resonances (ν17 and ν18) acts to raise the mean inclination of the surviving population of particles over 4 billion yr of interactions with Jupiter, Saturn…

INCLINATION MIXING IN THE CLASSICAL KUIPER BELT
We investigate the long-term evolution of the inclinations of the known classical and resonant Kuiper Belt objects (KBOs). This is partially motivated by the observed bimodal inclination distribution
EVIDENCE FOR SLOW MIGRATION OF NEPTUNE FROM THE INCLINATION DISTRIBUTION OF KUIPER BELT OBJECTS
Much of the dynamical structure of the Kuiper Belt can be explained if Neptune migrated over several AU, and/or if Neptune was scattered to an eccentric orbit during planetary instability. An
The dynamical stability of a Kuiper Belt-like region
The dynamics of the Kuiper Belt region between 33 and 63 au is investigated just taking into account the gravitational influence of Neptune. Indeed the aim is to analyse the information which can be
Not a simple relationship between Neptune's migration speed and Kuiper belt inclination excitation.
TLDR
It is concluded that the observed large inclination dispersion of Kuiper belt objects does not require Neptune's migration to be slow; planetary migration with e-folding timescales of 5, 10, 30, and 50 Myr can all yield inclination dispersions similar to the observed Plutino and hot classical populations, with no correlation between the degree of inclination excitation and migration speed.
The Kuiper Belt and the Primordial Evolution of the Solar System
We discuss the structure of the Kuiper belt as it can be inferred from the first decade of observations. In particular, we focus on its most intriguing properties — the mass deficit, the

Abstract We studied the orbital evolution of objects with initial orbits close to those of Jupiter-family comets (JFCs), Halley-type comets (HTCs), and long-period comets, and the probabilities of
Migration of Jupiter‐Family Comets and Resonant Asteroids to Near‐Earth Space
Abstract: The orbital evolution of about 26,000 Jupiter‐crossing objects and 1,500 resonant asteroids under the gravitationa influence of planets was investigated. The rate of their collisions with

Evidence for Early Stellar Encounters in the Orbital Distribution of Edgeworth-Kuiper Belt Objects
We show that early stellar encounters can explain the high eccentricities and inclinations observed in the outer part (>42 AU) of the Edgeworth-Kuiper Belt (EKB). We consider the proto-Sun as a
