More chips off of Asteroid (4) Vesta: Characterization of eight Vestoids and their HED meteorite analogs
2014, IcarusCitation Excerpt :While these works reported consistent Band I absorption centers, the Band II absorption centers are quite divergent and range from 1.914- to 1.980-μm (Kelley et al., 2003; Moskovitz et al., 2010). These band center variations, which could be attributed to surface mineralogical variations as well as other possible causes, produce meteorite analog candidates that range from the diogenites (Kelley et al., 2003) to the eucrites (Moskovitz et al., 2010). In addition, Reddy et al. (2011b) and De Sanctis et al. (2011b) have identified diogenite-like V-type asteroids.

Spectral diversity and photometric behavior of main-belt and near-Earth vestoids and (4) Vesta: A study in preparation for the Dawn encounter
2014, IcarusCitation Excerpt :Launched September 27, 2007, the spacecraft began the detailed study of the Main Belt Asteroid 4 Vesta with orbit insertion on July 17, 2011 and continuation of its orbital mission for 1 year. The main goals of Dawn’s in-depth study are to understand the evolution of this protoplanet and the role of water in its history; to derive Vesta’s bulk properties; to model its surface composition and geologic landforms, and to understand its relationship with the terrestrial HED meteorites and the near-Earth vestoids (Kelley et al., 2003; Binzel et al., 2004; Russell et al., 2012), both of which are believed to originate from Vesta. In preparation for the Dawn encounter, a ground-based observing campaign to study the spectrophotometric properties of vestoids was undertaken.

The origin of Vesta's crust: Insights from spectroscopy of the Vestoids
2011, IcarusCitation Excerpt :The remaining eight Vestoids appear to represent mixtures of both eucrite and diogenite materials. 1929 Kollaa has previously been suggested to have compositional characteristics similar to those of cumulate eucrites (Kelley et al., 2003). However, the spectra of howardites and cumulate eucrites are similar (Burbine et al., 2009).
