Abstract The formation process of Uranus and Neptune is numerically explored. By using a simple two-body approximation based on Opik's formalism, it is found that the accretion process in the outer planetary region usually leads to the formation of two large planets, the mass of the farther one being in most cases somewhat larger than that of the closer one, in agreement with the mass relation between Uranus and Neptune. In addition, some other protoplanets of up to a few Earth masses are found… Expand
Accretional origin of the giant planets and its consequences
The basic mass distribution and orbital structure of the Solar System are determined by the original mass and angular momentum of the solar nebula and planetary accretion effect. Dust-gas aerodynamicExpand
Effects of the planetary migration on some primordial satellites of the outer planets - I. Uranus’ case
Context. During the first hundred million years after the formation of our solar system, the four giant planets are believed to have migrated significantly (by up ≈20 AU). The current scenario andExpand
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
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 theExpand
Orbital Migration Of Giant Planets: Using Numerical Integration To Investigate Consequences For Other Bodies
A number of extrasolar planets have been detected in close orbits around nearby stars. It is probable that these planets did not form in these orbits but migrated from their formation locationsExpand
Orbital Perturbations of the Galilean Satellites During Planetary Encounters
The Nice model of the dynamical instability and migration of the giant planets can explain many properties of the present solar system, and can be used to constrain its early architecture. In theExpand
Numerical simulations of the accretion of Uranus and Neptune
Abstract The accretion process of the outer planets was one of the most collective phenomena during the formation of the solar system. From the region of the terrestrial planets up to its outermostExpand
The Formation of the Oort Cloud and the Primitive Galactic Environment
We analyze the conditions of formation of the Oort cloud from icy planetesimals scattered by the accreting outer planets. The combined effect of planetary and external perturbations is considered toExpand
Remarks on Modeling the Formation of Uranus and Neptune
We have studied two scenarios for the in situ formation of Uranus and Neptune from a hundred or so sub-Earth-sized planetary embryos initially on low-inclination, nearly circular orbits beyondExpand
Evolution of the Kuiper belt during the accretion of the outer planets
A set of self-consistent simulations of the formation of Uranus and Neptune are performed to study the evolution of the native KBOs in the process. Our main goal is to have a deeper understanding ofExpand

The dynamical evolution of bodies under the gravitational influence of the accreting proto-Uranus and proto-Neptune is investigated. The main aim of this study is to analyze the interrelationsExpand
Some dynamical aspects of the accretion of Uranus and Neptune: The exchange of orbital angular momentum with planetesimals
Abstract The final stage of the accretion of Uranus and Neptune is numerically investigated. The four Jovian planets are considered with Jupiter and Saturn assumed to have reached their presentExpand
The origin of Pluto's orbit: implications for the
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 extraordinaryExpand
Dynamical injection of Mars-sized planetoids into the asteroidal belt from the terrestrial planetary accretion zone
Abstract The simultaneous accretion and gravitational scattering of a system of planetoids in the terrestrial planetary region are examined by using a Monte Carlo model. The dynamical consequence ofExpand
On the number of planets in the outer solar system: Evidence of a substantial population of 1000-km bodies
Where have all the Tritons gone, long time ago? A natural consequence of the accumulation stage of planetary formation is the scattering of planetesimals during the accretion epoch. In the outerExpand
Dynamical processes of macro-accretion of Uranus and Neptune: A first look

Accumulation and migration of the bodies from the zones of giant planets
Within the model of solid-body accumulation of planets (or their nuclei) the accumulation and migration of bodies from the feeding zones of the giant planets are investigated. The investigation isExpand
Exchange of condensed matter among the outer and terrestrial protoplanets and the effect on surface impact and atmospheric accretion
Abstract One current picture of the accretion process of Uranus and Neptune invokes extensive gravitational scattering of the icy planetesimals by the photoplanets as they grew to significant masses.Expand

Inhibition of giant-planet formation by rapid gas depletion around young stars
Observations of the molecular gas surrounding 20 stars whose ages are likely to be in this range are reported, finding that the gas dissipates rapidly; after a few million years the mass remaining is typically much less than the mass of Jupiter. Expand
