We present here evidence that two previously unidentified, yet conspicuous gaps in Saturns rings lie at distances corresponding to 2/3 and 4/3 of the planets rotation period. Gaps such as these can be produced in a ring of large bodies or small uncharged particles only by a non-axisymmetric gravitational field (both of the above can be associated with the l = m = 3 harmonic), a fact that is relevant to models of planetary interiors.Anyone you share the following link with will be able to read this content:
