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 ) has orbital eccentricities significantly smaller than the limit imposed by stability constraints. Here, we confirm their result by looking at the orbital distribution and stability properties in proper element space. We show that the observed distribution could have been produced by the slow…

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 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
Forming the Cold Classical Kuiper Belt in a light Disk
Large Kuiper Belt Objects are conventionally thought to have formed out of a massive planetesimal belt that is a few thousand times its current mass. Such a picture, however, is incompatible with
De-biased populations of Kuiper belt objects from the deep ecliptic survey
The Deep Ecliptic Survey (DES) was a survey project that discovered hundreds of Kuiper Belt objects from 1998 to 2005. Extensive follow-up observations of these bodies has yielded 304 objects with
Unusual Eccentricity and Inclination Distributions of Trans-Neptunian Objects and Trans-Neptunian Binaries
The eccentricity and inclination of trans-Neptunian objects (TNOs) decrease significantly as radius of perihelion increases. Also, the percentage of TNOs in almost circular orbits with low

Abstract The present-day orbit distribution of the Neptune Trojans is a powerful probe of the dynamical environment of the outer Solar System during the late stages of planet migration. In this work,

JUMPING NEPTUNE CAN EXPLAIN THE KUIPER BELT KERNEL
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

Today, Pluto and Eris are the largest and most massive Trans-Neptunian Objects respectively. They are believed to be the last remnants of a population of planetesimals that has been reduced by >99%

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.
