摘要

我们报告了利用 FAST 在五个超新星遗迹（SNR）中搜索射电脉冲星的结果。观测是在快照模式下使用 19 波束接收器进行的。每个测点的积分时间为 10 分钟。我们在对 SNR G29.6+0.1 的观测中发现了一颗新的脉冲星 PSR J1845$-$0306，它的自旋周期为 983.6 ms，色散测量值为 444.6$\pm$2.0 cm$^{-3}$ pc。要判断脉冲星和SNR之间的联系，还需要进一步的验证。我们还在 SNR G29.6+0.1 和 G29.7$-$0.3 的数据中重新探测到了一些已知的脉冲星。在对其他三个自发核变星的观测中没有发现脉冲星。

A search for radio pulsars in supernova remnants using FAST with one pulsar discovered

We report on the results of a search for radio pulsars in five supernova remnants (SNRs) with FAST. The observations were made using the 19-beam receiver in the Snapshot mode. The integration time for each pointing is 10 min. We discovered a new pulsar PSR J1845$-$0306 which has a spin period of 983.6 ms and a dispersion measure of 444.6$\pm$2.0 cm$^{-3}$ pc in observations of SNR G29.6+0.1. To judge the association between the pulsar and the SNR, further verification is needed. We also re-detected some known pulsars in the data from SNRs G29.6+0.1 and G29.7$-$0.3. No pulsars were detected in observations of other three SNRs.
