Chiral Effective Field Theory is a Popperian (testable) theory on nuclear physics. We are still working out what a proton or a neutron actually Looks Like - that is, how it bounces off other particles (not just photons). On the small scale this is difficult. But if you get a whole star made of neutrons, by averages we should be able to get a good picture of the one neutron, or neutrons bound in atomic nuclei. Neutron-star-quakes are how we get a better view on the thing's deep innards; so far this blog has considered only quakes in softer stars like Ks.
At least, so I gather. The article from Bath Uni (and Ohio and the good ol' Texas Aggies) is one of those In-Search-Of deals. These go to the press to justify the departmental budget(s). But it does seem justifiable research.
