CASTAway: An Asteroid Main Belt Tour and Survey [PDF]
Advances in Space Research, 2018 CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the composition of these objects can be inferred from space-based remote sensing using spectroscopic techniques.

A Record of Planet Migration in the Main Asteroid Belt [PDF]
Nature, 2009 The main asteroid belt lies between the orbits of Mars and Jupiter, but the region is not uniformly filled with asteroids. There are gaps, known as the Kirkwood gaps, in the asteroid distribution in distinct locations that are associated with orbital resonances with the giant planets; asteroids placed in these locations follow chaotic orbits and escape

A Population of Comets in the Main Asteroid Belt
Science, 2006Comets are icy bodies that sublimate and become active when close to the Sun. They are believed to originate in two cold reservoirs beyond the orbit of Neptune: the Kuiper Belt (equilibrium temperatures of ∼40 kelvin) and the Oort Cloud (∼10 kelvin).

Subaru Main Belt Asteroid Survey (SMBAS)—Size and Color Distributions of Small Main-Belt Asteroids
Planetary and Space Science, 2007Abstract Since February, 2001, we have been conducting a series of survey observations to investigate the physical property of very small Main Belt Asteroids (sub-km MBAs) using the Subaru prime-focus camera (Suprime-Cam) attached to the 8.2 m Subaru telescope. We call our surveys “SMBAS: Subaru Main-Belt Asteroids Survey”.

Asteroid Proper Elements and the Dynamical Structure of the Asteroid Main Belt
Icarus, 1994Abstract We have computed proper elements for 12,573 asteroids, including all the ones with orbits accurate enough to be useful for family identification. This was done with an upgraded version of our iterative analytical algorithm, resulting in significantly improved accuracy for most asteroids in the low to moderate inclination and eccentricity ...

Discovery of a Basaltic Asteroid in the Outer Main Belt
Science, 2000Visible and near-infrared spectroscopic observations of the asteroid 1459 Magnya indicate that it has a basaltic surface. Magnya is at 3.15 astronomical units (AU) from the sun and has no known dynamical link to any family, to any nearby large asteroid, or to asteroid 4 Vesta at 2.36 AU, which is the only other known large basaltic asteroid.

The Main Belt as a Source of Near-Earth Asteroids
Earth, Moon, and Planets, 1996We investigate the flux of main-belt asteroid fragments into resonant orbits converting them into near-Earth asteroids (NEAs), and the variability of this flux due to chance inter asteroid al collisions. A numerical model is used, based on collision al physics consistent with the results of laboratory impact experiments.

The recent breakup of an asteroid in the main-belt region
Nature, 2002The 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 the large-scale collisions that shaped the planets during early epochs.

The number density of main‐belt asteroids
Astronomische Nachrichten, 1997AbstractIn this paper we have studied how the number density of asteroids varies as a function of the mean distance from the sun.

Olivine-rich asteroids in the main asteroid belt
2015Olivine-dominated asteroids, classified as A-types with near-infrared spectral measurements are largely thought to be the mantle remnants of disrupted differentiated small bodies. These A-type asteroids hold clues to asteroid differentiation and to the collisional history of those differentiated bodies.
