资源简介:
CCO pulsars are stable rotators with weak dipole B-fields and small spin-down rates. We have been timing two CCO pulsars for 20 years. In 2016 there was a glitch in 1E 1207.4-5209 comma which is unprecedented for a pulsar with such a small spin-down rate comma and has profound implications for the B-field evolution of CCOs and the mechanismopenParsclosePar that trigger glitches. We must continue to time this event to distinguish between a very slow glitch recovery and a permanent comma large increase in its spin-down rate. We see similar features in recent timing of PSR J0821-4300 in Puppis A comma and did initiate in October 2019 a new phase-connected timing solution to ensure a precise cycle count that will resolve the nature of its timing anomaly. This proposal is also to continue monitoring PSR J0821-4300.
