Therefore the discoverers , led by Geraint Jones of the Cassini MIMI team , argue that the depletions must be caused by solid particles orbiting Rhea : The simplest explanation for the symmetrical punctuations in plasma flow are `` extended arcs or rings of material '' orbiting Rhea in its equatorial plane .
