Vela-size glitch rates in youthful pulsars.

URAMA J.O. and OKEKE P.N.

Abstract (from CDS):

A total of 71 glitches (Δνν≥10–9) have been reported to date in 30 pulsars. 13 of these glitches come from the Vela pulsar, whose glitches are mostly of magnitude Δνν∼10–6. Only about 40per cent of the total glitches are of this magnitude. While glitches of this size have been observed from pulsars aged 104-107yr, 80per cent of them come from the youthful pulsars, aged 104-105yr. For pulsars older than 104yr, the glitch activity is found to be proportional to the logarithm of the spin-down rate, ν{dot}. Based on this relationship, we identify six other pulsars that are most likely to yield frequent large glitches. Since these pulsars are of comparable ages to the Vela pulsar, real-time glitch detection on them and studies of their subsequent recovery would play a vital role in improving understanding of the neutron star interior and the pulsar glitch mechanisms.
