from the development of new telescopic instruments (such as SpeX [Rayner, JT, and 7 …

The main belt is believed to have originally contained an Earth mass or more of material,
enough to allow the asteroids to accrete on relatively short timescales. The present-day …

The Dawn mission has provided new evidence strengthening the identification of asteroid
Vesta as the parent body of the howardite, eucrite, and diogenite (HED) meteorites. The …

Meteorites provide a unique insight into early Solar System processes. However, to fully
interpret this record requires that these meteorites are related back to their source asteroids …

We present the results of a visible spectroscopic survey of 820 asteroids carried on between
November 1996 and September 2001 at the 1.52 m telescope at ESO (La Silla). The …

Abstract Howardite-eucrite-diogenite (HED) meteorites, thought to be derived from 4 Vesta,
provide the best sampling available for any differentiated asteroid. However, deviations in …

Asteroids and comets are the remnants of the swarm of planetesimals from which the
planets ultimately formed, and they retain records of processes that operated prior to and …

Extensive collection efforts in Antarctica and the Sahara in the past 10 years have greatly
