Dynamical evolution of basaltic asteroids outside the dynamical Vesta family

<p>Basaltic V-type asteroids are the leftovers from the formation and evolution of the differentiated planetesimals. They are thought to originate from mantles of multiple different parent bodies. Identifying the links between individual V-type asteroids and multiple planetesimals is challenging, especially in the inner part of the Main Asteroid Belt where the majority of V-type asteroid is expected to originate from a fossil planetesimal (4) Vesta.</p> <p>We perform a 2Gy numerical integration of orbits of the selected V-type asteroids. For each asteroid we use 1001 clones to estimate the orbital uncertainties. In the integration we use information on physical properties of the considered V-type asteroids such as pole orientation, rotational period and thermal parameters. This may confirm the hypothesis that the number of differentiated basaltic objects in the Main Belt should be much higher than previously assumed. We show results for the ~25 V-type asteroids outside the dynamical Vesta family in the Main Asteroid Belt.</p>
