Numerical experiments on simple or symmetric ejections of massive bodies from the nucleus of a disk of stars are presented. The ejected masses range from 0.04 to 0.1 of the total mass. Either spiral features or a barred structure appear but do not last for a long time. Material arms start leading and become trailing.
