  Most Howardite-Eucrite-Diogenite (HED) meteorites (analogs to V-type
asteroids) are thought to originate from asteroid (4) Vesta. However, some HEDs
show distinct oxygen isotope ratios and therefore are thought to originate from
other asteroids. In this study, we try to identify asteroids that may represent
parent bodies of those mismatching HEDs. In particular, the origin of the
anomalous Bunburra Rockhole meteorite was traced back to the inner main
asteroid belt, showing that there might be asteroids that are not genetically
linked to the asteroid (4) Vesta (the main source of V-type asteroids and HED
meteorites) in the inner main belt. In this work we identify V-type asteroids
outside the dynamical Vesta family whose rotational properties (retrograde vs
prograde rotation) suggest the direction of Yarkovsky drift that sets them
apart from typical Vestoids and Vesta fugitives. Specifically Nesvorny et al.
2008 simulated escapes paths from the Vesta family and showed that typical
Vesta fugitives in the inner main asteroid belt at semi-major axis a < 2.3 AU
have to have retrograde rotations and physical and thermal parameters that
maximize the Yarkovsky force in order to evolve to scattered orbits within 1-2
Gyrs (age of the Vesta collisional family). Therefore large asteroids outside
the Vesta family and with a < 2.3 AU and having thermal and rotational
properties minimizing the Yarkovsky drift or showing Yarkovsky drift direction
towards (4) Vesta are the best candidates for non-Vestoids V-type asteroids and
therefore parent bodies of anomalous HED. In this study, we have performed
accurate photometric observations and determined sense of rotation for several
asteroids testing their links to Vesta and anomalous HED. We have found several
potential non-Vestoid candidates. Those objects have to be studied in more
detail to fully confirm their link to anomalous HEDs.
