摘要:

我们描述了搜索瞬态无线电发射源(如旋转无线电瞬变(RRAT))所涉及的步骤,并提出了10个新的瞬态无线电源中发现的帕克斯多波束脉冲星调查的重新分析。每个新的来源以及一个以前已知的来源的后续观察也提出。新的来源表明,瞬变射电发射中子星的数量,以及总的中子星数量,可能比最初预测的还要大。我们强调了单脉冲搜索的射频干扰切除的重要性。此外,我们还讨论了一些有趣的属性的个别来源,并考虑在精确定义RRAT和确定它们适合在与其他已知的中子星类所涉及的困难。

英文摘要:

We describe the steps involved in performing searches for sources of transient radio emission such as Rotating Radio Transients (RRATs), and present 10 new transient radio sources discovered in a re-analysis of the Parkes Multi-beam Pulsar Survey. Followup observations of each new source as well as one previously known source are also presented. The new sources suggest that the population of transient radio-emitting neutron stars, and hence the neutron star population in general, may be even larger than initially predicted. We highlight the importance of radio frequency interference excision for single-pulse searches. Also, we discuss some interesting properties of individual sources and consider the difficulties involved in precisely defining a RRAT and determining where they fit in with the other known classes of neutron stars.
