Well well! A ring is back in the reckoning, and this time originating from the breakup of a former sub-satellite. (I'm sure I've seen that somewhere before )

If those 'serious simulations' show ring edge warping at Iapetus from the distant Saturn, due to the Iapetan orbital inclination, then Joseph Burns' ideas and predictions about ring warping (born out already at Neptune) would neatly explain the short diverging attendant ridges. Check out the Planetary Rings chapter in The New Solar System. (I haven't seen the new edition, hope it is still included!)
Exciting times we live in! |

story just appeared in WiredScience! so i guess that officially makes it cool.
http://www.wired.com/wiredscience/2010/12/iapetus-ridge/ its an interesting story cause it continues to develop, and whatever the details about how the ring material got into orbit (there are several competing ideas tho most are related in some way), this feature exposed a new dynamical complexity to the Solar System. -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
