The June 1, 2006, issue of Nature has a new paper by Nimmo and Pappalardo entitled "Diapir-induced reorientation of Saturn's moon Enceladus" as well as an accompanying News and Views piece by Paul Hanlon. For the specific links, see the Editor's Summary.

The June 1, 2006, issue of Nature has a new paper by Nimmo and Pappalardo entitled "Diapir-induced reorientation of Saturn's moon Enceladus"...

I've read the paper and found it pretty interesting. I especially appreciate papers that offer ways to test the authors' hypotheses. For example, Nimmo and Pappalardo suggest "at least two additional tests. First, the distribution of impact craters—expected to show leading–trailing hemisphere asymmetry if the satellite orbits synchronously—will be affected by, and could constrain, reorientation. Second, Fig. 2 shows that a negative, long-wavelength gravity anomaly (with an amplitude of a few mGal at 200 km spacecraft altitude) will be associated with the anomalous south polar region. Regional gravity anomalies similar to this have been detected at Ganymede by the Galileo spacecraft." (References omitted).

For those without access to Nature, perhaps Nimmo may offer the paper on his publications page. Or the co-author, Bob Pappalardo, may have a suggestion
