Tytuł: The tale of differentiated planetesimals: Evidence from basaltic asteroids
The early Solar System was populated with numerous differentiated (into iron core, silicate mantle and crust) planetesimals. These objects evolved and grew into planets. Some were destroyed in collisions. Crust fragments of those bodies can still be observed in the main asteroid belt as basaltic V-type asteroids. In this project we have determined spins and shapes of V-type asteroids with the aim to reconcile them with numerical simulations of Nesvorny et al. 2008 and the planetesimal formation theory of Bottke et al. 2006.
