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 outstanding problem with the existing formation models is that the distribution of orbital inclinations they predicted is narrower than the one inferred from observations. Here we perform numerical simulations of Kuiper belt formation starting from an initial state with Neptune at 20 = 10 Myr and a_{N,0… 
Checking the compatibility of the cold Kuiper belt with a planetary instability migration model
Abstract The origin of the orbital structure of the cold component of the Kuiper belt is still a hot subject of investigation. Several features of the solar system suggest that the giant planets
GENERATION OF HIGHLY INCLINED TRANS-NEPTUNIAN OBJECTS BY PLANET NINE
The trans-Neptunian region of the solar system exhibits an intricate dynamical structure, much of which can be explained by an instability-driven orbital history of the giant planets. However, the
Dynamical effects on the classical Kuiper belt during the excited-Neptune model
Abstract The link between the dynamical evolution of the giant planets and the Kuiper Belt orbital structure can provide clues and insight about the dynamical history of the Solar System. The
THE ORBITAL DISTRIBUTION OF TRANS-NEPTUNIAN OBJECTS BEYOND 50 au
The dynamical structure of the Kuiper Belt beyond 50 au is not well understood. Here we report results of a numerical model with long-range, slow, and grainy migration of Neptune. The model implies
Kuiper belt: Formation and evolution
Abstract This chapter reviews accretion models for Kuiper belt objects (KBOs), discussing in particular the compatibility of the observed properties of the KBO population with the streaming
Kuiper Belt–like Hot and Cold Populations of Planetesimal Inclinations in the β Pictoris Belt Revealed by ALMA
The inclination distribution of the Kuiper belt provides unique constraints on its origin and dynamical evolution, motivating vertically resolved observations of extrasolar planetesimal belts. We
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.
Evidence for very early migration of the Solar System planets from the Patroclus–Menoetius binary Jupiter Trojan
The orbital distribution of trans-Neptunian objects provides strong evidence for the radial migration of Neptune1,2. The outer planets’ orbits are thought to have become unstable during the early
Positions of the secular resonances in the primordial Kuiper Belt disk
Abstract The dynamically hot and cold populations of the Kuiper Belt probably formed from two distinct regions of the Solar System. The former originated from a massive planetesimal disk extending
The Structure of the Distant Kuiper Belt in a Nice Model Scenario
This work explores the orbital distribution of minor bodies in the outer Solar System emplaced as a result of a Nice model migration from the simulations of Brasser & Morbidelli (2013). This

The formation of the Kuiper belt by the outward transport of bodies during Neptune's migration
TLDR
It is shown that the objects currently observed in the dynamically cold Kuiper belt were most probably formed within ∼35 au and were subsequently pushed outward by Neptune's 1:2 mean motion resonance during its final phase of migration.
Dynamical Implantation of Objects in the Kuiper Belt
Several models have been suggested in the past to describe the dynamical formation of hot Kuiper Belt objects (hereafter Hot Classicals or HCs for short). Here, we discuss a dynamical mechanism that

The existence of extremely wide binaries in the low-inclination component of the Kuiper Belt provides a unique handle on the dynamical history of this population. Some popular frameworks of the

We present a new analysis of the currently available orbital elements for the known Kuiper belt objects. In the nonresonant, main Kuiper belt, we find a statistically significant relationship between

The origin of the highly eccentric, inclined, and resonance-locked orbit of Pluto has long been a puzzle. A possible explanation has been proposed recently which suggests that these extraordinary
Evidence from the asteroid belt for a violent past evolution of Jupiter's orbit
We use the current orbital structure of large (>50 km) asteroids in the main asteroid belt to constrain the evolution of the giant planets when they migrated from their primordial orbits to their
