Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
The petrology record on the Moon suggests that a cataclysmic spike in the cratering rate occurred ∼700 million years after the planets formed; this event is known as the Late Heavy Bombardment (LHB).Expand

Origin of the orbital architecture of the giant planets of the Solar System
Planetary formation theories suggest that the giant planets formed on circular and coplanar orbits. The eccentricities of Jupiter, Saturn and Uranus, however, reach values of 6 per cent, 9 per centExpand

Chaotic capture of Jupiter's Trojan asteroids in the early Solar System
Jupiter's Trojans are asteroids that follow essentially the same orbit as Jupiter, but lead or trail the planet by an angular distance of ∼60 degrees (co-orbital motion). They are hypothesized to beExpand

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

An Archaean heavy bombardment from a destabilized extension of the asteroid belt
The barrage of comets and asteroids that produced many young lunar basins (craters over 300 kilometres in diameter) has frequently been called the Late Heavy Bombardment (LHB). Many assume the LHBExpand

Asteroids Were Born Big
Abstract How big were the first planetesimals? We attempt to answer this question by conducting coagulation simulations in which the planetesimals grow by mutual collisions and form larger bodies andExpand

The recent breakup of an asteroid in the main-belt region
The present population of asteroids in the main belt is largely the result of many past collisions. Ideally, the asteroid fragments resulting from each impact event could help us understand theExpand

Recent Origin of the Solar System Dust Bands
Infrared Astronomical Satellite (IRAS) observations in 1983 revealed the existence of several solar system dust bands. These dust bands are believed to be debris produced by recent disruption eventsExpand

Evidence for two populations of classical transneptunian objects : The strong inclination dependence of classical binaries
Abstract We have searched 101 Classical transneptunian objects for companions with the Hubble Space Telescope. Of these, at least 21 are binary. The heliocentric inclinations of the objects weExpand

We revisit the issue of the cause of the dynamical instability during the so-called Nice model, which describes the early dynamical evolution of the giant planets. In particular, we address theExpand
