On a ring origin of the equatorial ridge of Iapetus Options

[Guest_AlexBlackwell_*]

Wing Ip just had an interesting Iapetus-related paper published in GRL.

I also point out that the New Solar System books' chapter on Planetary Rings describes the 'bump' process that occurs in ring systems and naturally causes them to spread, without any outside influences at all.

(I suspect outside influences did play a role in the evolution of this putative ring system, most notably drag forces from Poynting Robertson effects, and solar wind/Saturn magnetotail interactions, that resulted in the entire ring system emplacing on the surface, and not also concurrently generating some small satellites just outside the Iapetan Roche limit)
