Phys. Rev. Lett. 91, 101101 (2003) [4 pages]Constraining Hadronic Superfluidity with Neutron Star PrecessionReceived 19 February 2003; published 3 September 2003 I show that the standard picture of the neutron star core containing coexisting neutron and proton superfluids, with the proton component forming a type II superconductor threaded by flux tubes, is inconsistent with observations of long-period (∼1 yr) precession in isolated pulsars. I conclude that either the two superfluids coexist nowhere in the stellar core, or the core is a type I superconductor rather than type II. Either possibility would have interesting implications for neutron star cooling and theories of spin jumps (glitches). © 2003 The American Physical Society URL:
