The Kuiper Belt is a population of icy bodies beyond the orbit of Neptune. A particularly puzzling and up-to-now unexplained feature of the Kuiper Belt is the so-called ?kernel,? a concentration of orbits with semimajor axes a ? 44 AU, eccentricities e ? 0.05, and inclinations . Here we show that the Kuiper Belt kernel can be explained if Neptune?s otherwise smooth migration was interrupted by a discontinuous change of Neptune?s semimajor axis when Neptune reached ?28 AU. Before the… 
Neptune's Orbital Migration Was Grainy, Not Smooth
The Kuiper belt is a population of icy bodies beyond the orbit of Neptune. The complex orbital structure of the Kuiper belt, including several categories of objects inside and outside of resonances
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
Tracking Neptune's Migration History through High-Perihelion Resonant Trans-Neptunian Objects
Recently, Sheppard et al. (2016) presented the discovery of seven new trans-Neptunian objects with moderate eccentricities, perihelia beyond 40 AU, and semimajor axes beyond 50 AU. Like the few
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
Beyond the Kuiper Belt Edge: New High Perihelion Trans-Neptunian Objects with Moderate Semimajor Axes and Eccentricities
We have been conducting a survey for distant solar system objects beyond the Kuiper Belt edge (~50 AU) with new wide-field cameras on the Subaru 8 meter and CTIO 4 meter telescopes. We are interested
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
The planet nine hypothesis
Over the course of the past two decades, observational surveys have unveiled the intricate orbital structure of the Kuiper Belt, a field of icy bodies orbiting the Sun beyond Neptune. In addition to
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 evolution of asteroids in the jumping-Jupiter migration model
In this work, we investigate the evolution of a primordial belt of asteroids, represented by a large number of massless test particles, under the gravitational effect of migrating Jovian planets in
Origin and Evolution of Short-period Comets
Comets are icy objects that orbitally evolve from the trans-Neptunian region (the Kuiper belt and beyond) into the inner Solar System, where they are heated by solar radiation and become active due

The current dynamical structure of the Kuiper Belt was shaped by the orbital evolution of the giant planets, especially Neptune, during the era following planet formation when the giant planets may

Neptune's dynamical history shaped the current orbits of Kuiper Belt objects (KBOs), leaving clues to the planet's orbital evolution. In the 'classical' region, a population of dynamically 'hot'
Origin of the peculiar eccentricity distribution of the inner cold Kuiper belt
Abstract Dawson and Murray-Clay (Dawson and Murray-Clay [2012]. Astrophys. J., 750, 43) pointed out that the inner part of the cold population in the Kuiper belt (that with semi major axis a 43.5 AU

I simulate the orbital evolution of the four major planets and a massive primordial planetesimal disk composed of 104 objects, which perturb the planets but not themselves. As Neptune migrates by
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.

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
Orbital Evolution of Planets Embedded in a Planetesimal Disk
The existence of the Oort comet cloud, the Kuiper belt, and plausible inefficiencies in planetary core formation all suggest that there was once a residual planetesimal disk of mass ~10–100 M⊕ in the
On the Plutinos and Twotinos of the Kuiper Belt
We illuminate dynamical properties of Kuiper belt objects (KBOs) in the 3 : 2 (Plutino) and 2 : 1 ("Twotino") Neptunian resonances within the model of resonant capture and migration. We analyze a
A COLLISIONAL FAMILY IN THE CLASSICAL KUIPER BELT
The dynamical evolution of classical Kuiper belt objects (CKBOs) is divided into two parts, according to the secular theory of test particle orbits. The first part is a forced oscillation driven by
Shaping the Kuiper belt size distribution by shattering large but strengthless bodies
The observed size distribution of Kuiper belt objects (KBOs)—small icy and rocky Solar System bodies orbiting beyond Neptune—is well described by a power law at large KBO sizes. However, recent work
