Several properties of the Solar System, including the wide radial spacing of the giant
planets, can be explained if planets radially migrated by exchanging orbital energy and …

Comets have three known reservoirs: the roughly spherical Oort Cloud (for long-period
comets), the flattened Kuiper Belt (for ecliptic comets), and, surprisingly, the asteroid belt (for …

Chondrules are millimeter-sized spherules that dominate primitive meteorites (chondrites)
originating from the asteroid belt. The incorporation of chondrules into asteroidal bodies …

The distribution of asteroids across the main belt has been studied for decades to
understand the current compositional distribution and what that tells us about the formation …

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 …

To date, no accretion model has succeeded in reproducing all observed constraints in the
inner Solar System. These constraints include:(1) the orbits, in particular the small …

Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally
stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large …

Jupiter Trojans are thought to be survivors of a much larger population of planetesimals that
existed in the planetary region when planets formed. They can provide important constraints …

We use the current orbital structure of large (> 50 km) asteroids in the main asteroid belt to
constrain the evolution of the giant planets when they migrated from their primordial orbits to …

The asteroid belt is found today in a dramatically different state than that immediately
following its formation. It is estimated that it has been depleted in total mass by a factor of at …
