Observational Constraints on the Role of the Crust in the Post-glitch Relaxation
arXiv:astro-ph/0508022 · doi:10.1016/j.newast.2005.07.004
Abstract
The observed large rates of spinning down after glitches in some radio pulsars have been previously explained in terms of a long-term spin-up behavior of a superfluid part of the crust of neutron stars. We argue that the suggested mechanism is not viable; being inconsistent with the basic requirements for a superfluid spin-up, in addition to its quantitative disagreement with the data. Hence, the observed post-glitch relaxations may not be interpreted due only to the effects of the stellar crust.
