Glitches and pinned vorticity in the Crab pulsar

AUTOR(ES)

Alpar, M. A.

RESUMO

We suggest that the glitch behavior observed in the Crab pulsar is associated with vorticity jumps induced by a starquake or a comparable external fluctuation in the weakly pinned vortex region expected in the crust of a young neutron star, and that the differences in the glitch behavior of the Crab, Vela, and older pulsars may be explained on evolutionary grounds.
