Title: Testing the dynamical link between HED meteorites and V-type asteroids in the inner main belt

Abstract: Most howardite-eucrite-diogenite meteorites (HEDs) are generally thought to be collisionaly ejected debris from asteroid (4) Vesta. However, several of the HED group meteorites (for example Bunburra Rockhole, Ibitra, Pasamonte, PCA 91007, NWA 011, A-881394, and others) show oxygen isotope ratios suggesting that they must have originated in multiple other asteroids. Those asteroids are parts of disrupted planetesimals - first bodies that formed in the Solar System four billion years ago. Identification of those asteroids, confirmation of their link to the anomalous meteorites, determination of their properties and distribution in Solar System is essential to understanding early phases of planetary formation and evolution.
