Scientific paper

We have recently discovered at Parkes PSR J1833-1034, the pulsar born in the explosion that also gave rise to the supernova remnant (SNR) G21.5-0.9. The age of the system is likely < 1000 years, and J1833-1034 is probably among the 2-3 youngest pulsars known in the Galaxy. Using Parkes data (P509) obtained from the initial monitoring of the rotation of this pulsar, we have already been able to measure its "braking index", n ~ 2, one of only a handful of such measurements existing. We here request a final 6 months (24 hours) of telescope time to monitor this faint pulsar, in order to determine its braking index with the high precision necessary for comparison with those of other pulsars and for learning about its rotational history and evolution of the pulsar/SNR system, and also to improve the present uncertainty on its celestial coordinates.
