Scientific paper

The response of the Vela pulsar (PSR0833-45) following each of seven giant glitches, a recovery on two timescales of about 6 and 60 days, has been interpreted as evidence for the existence of distinct regions of neutron superfluid within the stellar core. Observations are reported here that started 35 minutes after the eighth glitch of PSR0833-45 which reveal a hitherto unseen glitch component: a (12 + or - 1) percent increase in the slowdown rate, most of which decayed over 0.4 days. These data support the existence of at least to superfluid components in the stellar crust that are coupled linearly to the normal crust.
