The influence of recent major crater impacts on the surrounding surfaces of (21) Lutetia

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 50 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 25-30 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.
