论文摘要
我们使用Parkes 64 \,M射电望远镜进行了两个间歇性脉冲星的长期观察,即PSRS〜J1832+0029和J1841 $ -0500。这些脉冲星的无线电发射“关闭”了为期一年的持续时间。我们的新观察结果使我们能够改善对开关时间尺度的确定,并在这些排放状态下的降低率降低率。总的来说,我们的结果与以前对这些脉冲星的研究一致,但是我们现在的数据跨度更长。 We have identified two unexpected signatures in the data.在“关闭”排放状态下对PSR〜J1832 $+$ 0029的单一观察中发现了弱排放。对于PSR〜J1841 $ - $ 0500,我们确定了可检测到的单个脉冲的强度的准周期波动,调制周期在21到36个脉冲周期之间。
We present long-term observations of two intermittent pulsars, PSRs~J1832+0029 and J1841$-$0500 using the Parkes 64\,m radio telescope. The radio emission for these pulsars switches "off" for year-long durations. Our new observations have enabled us to improve the determination of the on-off timescales and the spin down rates during those emission states. In general our results agree with previous studies of these pulsars, but we now have significantly longer data spans. We have identified two unexpected signatures in the data. Weak emission was detected in a single observation of PSR~J1832$+$0029 during an "off" emission state. For PSR~J1841$-$0500, we identified a quasi-periodic fluctuation in the intensities of the detectable single pulses, with a modulation period between 21 and 36 pulse periods.
