Description:
We study the expectancy of large glitches
(ΔΩ/Ω>10^-7) from a sample of 430 pulsars other than
the Vela pulsar. The pulsars in this sample have exhibited 19 large
glitches. We assume that all pulsars experience such glitches, with
rates that depend on the pulsar's rotation rate omega and spin-down
rate omega, and on the glitch model. We use the core-quake model, and
two variants of the superfluid vortex unpinning model, and choose
model parameters such that the observed number of glitches is matched
by the theoretically expected number. Among the models investigated,
one of the superfluid vortex unpinning models gives good agreement
with the observed distribution of glitches and with the parameter
values deduced for the Vela pulsar glitches.
