A Numerical Approach to Study Ablation of Large Bolides: Application to Chelyabinsk

<div>A casual photograph of the Chelyabinsk bolide taken by Marat Ahmetvaleev. (a) The abrupt fragmentation at a height of 23 km is clearly distinguishable by the main flare. (b) Pictures of the dust trail by the same photographer reveal multiple paths produced by the fragments. Both pictures are courtesy of the author.</div>
