'Grand Unification' in Neutron Stars

The last decade has shown us that the observational properties of neutron stars are astonishingly diverse. From magnetars to rotating radio transients (RRATs), from radio pulsars (PSRs) to 'isolated neutron stars' (INSs), from central compact objects (CCOs) to millisecond pulsars (MSPs), observational manifestations of neutron stars are surprisingly assorted, with many properties totally unpredicted. The challenge is to establish an overarching physical theory of neutron stars and their birth properties that can explain this great diversity. Here I survey the different neutron stars classes, describe their properties, and discuss a possible 'grand unifying' model to explain why such at-first-glance simple compact objects can exhibit so many amazing phenomena.
