The Size Distribution of Trans-Neptunian Bodies*
We search 0.02 deg 2 of the invariable plane for trans-Neptunian objects (TNOs) 25 AU or more distant using the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope. With 22 ks perExpand
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
The Origin of Planetary Impactors in the Inner Solar System
TLDR
Old craters from a unique period of heavy bombardment that ended ∼3.8 billion years ago were made by asteroids that were dynamically ejected from the main asteroid belt, possibly due to the orbital migration of the giant planets. Expand
The origin of Pluto's peculiar orbit
THE origin of Pluto's unusual orbit—the most eccentric and inclined of all the planets—remains a mystery. The orbits of Pluto and Neptune overlap, but close approaches of these two planets areExpand
Neptune’s Migration into a Stirred-Up Kuiper Belt: A Detailed Comparison of Simulations to Observations
We use N-body simulations to examine the consequences of Neptune's outward migration into the Kuiper Belt, with the simulated end states being compared rigorously and quantitatively to theExpand
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
Dynamical erosion of the asteroid belt and implications for large impacts in the inner Solar System
Abstract The cumulative effects of weak resonant and secular perturbations by the major planets produce chaotic behavior of asteroids on long timescales. Dynamical chaos is the dominant lossExpand
The Debris Disk Around HR 8799
We have obtained a full suite of Spitzer observations to characterize the debris disk around HR 8799 and to explore how its properties are related to the recently discovered set of three massiveExpand
THE DYNAMICS OF KNOWN CENTAURS
We have numerically investigated the long-term dynamical behavior of known Centaurs. This class of objects is thought to constitute the transitional population between the Kuiper belt and theExpand
Long-term cycling of Kozai-Lidov cycles: extreme eccentricities and inclinations excited by a distant eccentric perturber.
TLDR
The very long-term evolution of the hierarchical restricted three-body problem is calculated analytically for high inclinations by averaging for the first time the double averaged secular equations of motion over the Kozai-Lidov Cycles and finding a new constant of the motion. Expand
