Abstract
We show that Neptune-scattered planetesimals of a few Earth masses could
have excited the eccentricities of the vast majority of
bodies in the primordial Edgeworth-Kuiper belt. This could result in
sculpting the belt to its currently observed structure and in
depleting most of its primordial mass by: (i) injecting most of the
bodies from the stable into the unstable regions in the inner belt;
(ii) enhancing the role of mutual catastrophic collisions in the outer
belt.
