Pulsar astrophysics : the glitch phenomenon

We briefly discuss a handful of topics in pulsar astrophysics, first some general well-known features, then an overview of the glitch phenomenon and the sort of information gathered about the internal structure and dynamics, and finally the quandary posed by the precession of PSR B1828-11 a very important clue pointing towards a novel paradigm for structure of the core regions. We point out that “exotic” solutions for the precession puzzle would force a consideration of exotic {\it glitch} mechanisms as well.
