The F-ring of Saturn shows a spirally wound edge. I have deduced its qualitative behaviour in section 2.4 of “New Evidence for the Dual Vector Field Theory for Gravitation (Cassini-Huygens Mission)”. These spirals form regular buds with an amplitude and a wavelength. The aim of this paper is to show the relationship between the physical dimensions of the buds and the orbital velocity of the F-ring’s edge.
