Escaping From the Asteroid Belt
Science, 1999Recent observations may have fingered the type of asteroid responsible for most meteorites (see main text). And thanks to progress in orbital dynamics, another mystery may also be yielding: how asteroid debris is slung toward Earth in the first place.

A Study of Chaos in the Asteroid Belt
1999Laskar’s results [1] on the chaotic motion of the inner planets, the existence of chaotic regions inside orbital resonances of asteroids, the movement of the rotational axis of Mars [2] and ultimately Earth’s unstable obliquity [3] brought the interest of astronomers back to the problem of chaos in the solar system.

Rogue Asteroids in the Inner Main Asteroid Belt
2014Very red featureless asteroids (spectroscopic D-types) are common among Jupiter Trojans, Hildas, and the outer main belt, and are thought to have formed in the outer solar system. Dynamical models of planetary migration and orbital drift by the Yarkovsky effect predict these D-types could have been transported as close to the sun as the middle main ...

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.

Focusing the Asteroid Belt of Organizations
Journal of Management Inquiry, 2008Concurring with Barley's pessimism that we do neglect the study of how corporations seek to influence and perhaps have captured the State, this text suggests two starting points that can give theoretical and practical leverage to investigate those issues.

The chemical structure of the asteroid belt
2018The asteroid main belt between Mars and Jupiter holds evidences fromthe early Solar System history. Built from the originally thin andstratified accretion disk, it has been scrambled by planetary migrations,resulting in a dynamical excitement and radial mixing of compositions.Since the 1970s,spectral surveys have characterized the surface compositions ...
