Merging of stellar systems is investigated by means of N-body simulations. We discuss the synchronization instability to trigger sudden merging, the origin of the ellipticity in the merger remnants, the distribution of stars in the halo, and the survival of the colour gradient of stars against the violent relaxation of the merging process.
