Abstract
Time series of the surface velocity fields resulting from the simulated impacts are also presented. It is suggested that the surface velocity field and velocity shear may play a role in the generation of lineaments. Our model calculations show that the velocity field lines around 50Â s after impact exhibit a reasonable qualitative correlation with the orientation of lineaments observed on the entire visible surface of Lutetia. It is also shown that incorporation of a core of 25-30Â km in diameter does not modify the velocity field evolution with time and, as such, the presence or otherwise of such a core cannot be inferred from lineament observations if this concept for their formation is valid.
