The Long-Term Dynamical Behavior of Short-Period Comets
We have developed and carefully tested a new computer code to follow the long-term dynamical evolution of a swarm of test particles in the solar system. This new integrator is approximately an orderExpand
From the Kuiper Belt to Jupiter-Family Comets: The Spatial Distribution of Ecliptic Comets☆
Abstract We present numerical orbital integrations of thousands of massless particles as they evolve from Neptune-encountering orbits in the Kuiper belt for up to 1 Gyr or until they either impact aExpand
A Multiple Time Step Symplectic Algorithm for Integrating Close Encounters
We present a new symplectic algorithm that has the desirable properties of the sophisticated but highly efficient numerical algorithms known as mixed variable symplectic (MVS) methods and that, inExpand
A disk of scattered icy objects and the origin of Jupiter-family comets.
Two recently discovered objects, 1996 RQ20 and 1996 TL66, have orbital elements similar to those predicted for objects in this disk, suggesting that they are thus far the only members of this disk to be identified. Expand
The Formation and Extent of the Solar System Comet Cloud
The formation of the solar system comet cloud and its subsequent evolution over an interval equal to the age of the solar system are simulated. Assuming that the comets formed in the outer planetaryExpand
Dynamical Lifetimes of Objects Injected into Asteroid Belt Resonances
Numerical simulations of particles placed in orbital resonances in the main asteroid belt show that the typical dynamical lifetimes of objects that could become near-Earth asteroids or meteorites areExpand
The long-term evolution of orbits in the solar system: A mapping approach
Abstract We derive a mapping that approximates the restricted circulat three-body problem (Sun, planet, test particle) when the eccentricity ofr test particle is small and its semimajor axis is closeExpand
A Three Million Year Integration of the Earth's Orbit
The equations of motion of the nine planets and the Earth's spin axis are integrated for 3.05 million years into the past. The equations include the dominant relativistic corrections and correctionsExpand
Growing the gas-giant planets by the gradual accumulation of pebbles
It is reported that pebbles form slowly enough to allow the planetesimals to gravitationally interact with one another, which typically leads to the formation of one to four gas giants between 5 and 15 astronomical units from the Sun, in agreement with the observed structure of the Solar System.
