I wrote about the discovery of possible rings around Saturn’s moon Rhea last week… and now Emily has the actual data. I’ll say, to my eye – and I’ve examined a lot of plots like that – that’s pretty convincing evidence that something is going on. I’d like to see corroborating data, but this is certainly enough to be interesting.
In the plot on Emily’s page, the dips in the number of electons counted shows where the rings may be. They also have a diagram where the rings are shown as circles, and the fit isn’t great. I wonder if anyone tried fitting similar ellipses? I’ll have to poke around and find out.
