The results show that the sweeping of mean motion resonances associated with planetary migration efficiently destabilizes orbits in the outer asteroid belt on a time scale of 10 million years, which provides an explanation for the observed depletion of asteroids in that region.

A record of planet migration in the main asteroid belt

It is shown that the observed distribution of main belt asteroids does not fill uniformly even those regions that are dynamically stable over the age of the Solar System, particularly just outward of the Kirkwood gaps associated with the 5:2, the 7:3 and the 2:1 Jovian resonances.

Dynamical History of the Asteroid Belt and Implications for Terrestrial Planet Bombardment

The main asteroid belt spans ~2-4 AU in heliocentric distance and is sparsely populated by rocky debris. The dynamical structure of the main belt records clues to past events in solar system history.…

Primordial Excitation and Depletion of the Main Belt

The asteroid belt is characterized by a large dynamical excitation, an important mass depletion compared to its original density, and a radial mixing of bodies with different physical and chemical…

Migration of giant planets in planetesimal discs

Planets orbiting a planetesimal circumstellar disc can migrate inward from their initial positions because of dynamical friction between planets and planetesimals. The migration rate depends on the…

About 4 billion years ago, the terrestrial planets were bombarded by asteroids following an orbital shake-up of the outer Solar System. Lunar samples, planetary cratering records and dynamical models…
