Planets are believed to have formed through the accumulation of a large number of small bodies. In the case of the gas-giant planets Jupiter and Saturn, they accreted a significant amount of gas directly from the protosolar nebula after accumulating solid cores of about 5–15 Earth masses. Such models, however, have been unable to produce the smaller ice giants Uranus and Neptune at their present locations, because in that region of the Solar System the small planetary bodies will have been more… Expand

THE FORMATION OF URANUS AND NEPTUNE AMONG JUPITER AND SATURN
The outer giant planets, Uranus and Neptune, pose a challenge to theories of planet formation. They exist in a region of the solar system where long dynamical timescales and a low primordial densityExpand
The accretion of Uranus and Neptune by collisions among planetary embryos in the vicinity of Jupiter and Saturn
Context. Modeling the formation of the ice giants Uranus and Neptune has been a challenging problem in planetary science for a long time. Owing to gas-drag, collisional damping, and resonantExpand
THE FORMATION OF URANUS AND NEPTUNE: CHALLENGES AND IMPLICATIONS FOR INTERMEDIATE-MASS EXOPLANETS
In this paper we investigate the formation of Uranus and Neptune, according to the core-nucleated accretion model, considering formation locations ranging from 12 to 30 AU from the Sun, and withExpand
Modes of Gaseous Planet Formation
The discovery of gas giant planets around nearby stars has launched a new era in our understanding of the formation and evolution of planetary systems. However, none of the over four dozen companionsExpand
Accretion of Uranus and Neptune from inward-migrating planetary embryos blocked by Jupiter and Saturn
Reproducing Uranus and Neptune remains a challenge for simulations of solar system formation. The ice giants' peculiar obliquities suggest that they both suffered giant collisions during theirExpand
Formation of Gas Giant Planets
The observed physical properties and orbits of giant planets, models of their internal structure and observations of protoplanetary disks provide constraints on the formation of gas giant planets.Expand
The formation of Uranus and Neptune in solid-rich feeding zones: Connecting chemistry and dynamics
Abstract The core accretion theory of planet formation has at least two fundamental problems explaining the origins of Uranus and Neptune: (1) dynamical times in the trans-saturnian solar nebula areExpand
Formation of the Cores of the Outer Planets
AbstractThe formation of the giant planets seems to be best explained by accretion of planetesimals to form massive cores, which in the case of Jupiter and Saturn were able to capture nebular gas.Expand
RAPID FORMATION OF OUTER GIANT PLANETS BY DISK INSTABILITY
The formation mechanism of the ice giant planets is uncertain. A new hypothesis envisions rapid formation of several gaseous protoplanets in a marginally gravitationally unstable protoplanetary disk,Expand
Rapid collisional evolution of comets during the formation of the Oort cloud
TLDR
It appears that collisions will prevent most comets escaping from most locations in the region of the giant planets until the disk mass there declines sufficiently that the dynamical ejection timescale is shorter than the collisional lifetime. Expand
