Neutron star dynamics, braking indices and energy dissipation

Models of pulsar glitches and postglich relaxation are reviewed. Implications for braking indices due to internal torques in the neutron star, and energy dissipation by internal torques are discussed. All recent observations of pulsars with large (Vela pulsar like) glitches and second derivatives are seen to fit with the same glitch dynamics that the Vela pulsar exhibits.
