dc.description.abstract | In the last twenty-five years several small basaltic V-type asteroids have been identified all around the main belt. Most of them are members of the Vesta dynamical family, but an increasingly large number appear to have no link with it. The question that arises is whether all these basaltic objects do indeed come from Vesta. In the light of the Dawn mission, who visited Vesta in 2011-2012, recent works were dedicated to the observation of several new V-type asteroids and their comparison with laboratory data (Fulvio et al., \cite{Fulvio2015}), and to a statistical analysis of the spectroscopic and mineralogical properties of the largest sample of V-types ever collected (Ieva et al., \cite{Ieva2015}, with the objective to highlight similarities and differences among objects belonging and not belonging to the Vesta dynamical family. Laboratory experiments support the idea that V-type NEAs spectral properties could be due to a balance of space weathering and rejuvenation processes triggered by close encounters with terrestrial planets. Statistical analysis shows that although most of the V-type asteroids in the inner main belt do have a surface composition compatible with Vesta family members, this seem not to be the case for V-types in the middle and outer main belt. For these Middle and Outer V-types (MOVs), their sizes, spectral parameters and location far away from the Vesta dynamical region point to a different origin than Vesta. | en_US |
