无线电发射器中的微故障：奇怪的金块的作用
Microglitches in radio pulsars: the role of strange nuggets
摘要：
奇异的金块被认为是早期宇宙的遗迹之一。由于它们的电荷质量比很低，所以看起来像是暗物质。它们的分布被认为与暗物质的分布相同。因此，它们可能被高磁场物体吸积，它们与恒星的碰撞是不可避免的。脉冲星毛刺通常被视为脉冲星频率的突然自旋。对于造成这种现象的机制，仍然是一个公开辩论。然而，脉冲星自旋频率有一类突然变化，称为微毛刺。这些事件的特征是脉冲星自旋频率（$ δν/ν\approx \pm 10^{-9}$）的突然微小变化。显然，在一些事件中看到的负信号与已知的故障机制不一致。在这个分析中，我们认为，吸积奇怪的金块与恒星可以很容易地引起微故障事件。这些事件的特征取决于奇怪的金块的能量和相互作用线。
英文摘要：
Strange Nuggets are believed to be among the relics of the early universe. They appear as dark matter due to their low charge-to-mass ratio. Their distribution is believed to be the same as that of dark matter. As such, they could be accreted by high magnetic field objects and their collisions with pulsars are inevitable. Pulsar glitches are commonly seen as sudden spin-ups in pulsar frequency. It is still an open debate with regard to mechanisms giving rise to such a phenomenon. However, there is a class of sudden changes in pulsar spin frequency known as microglitches. These event are characterized by sudden small change in pulsar spin frequency ($ δν/ν\approx \pm 10^{-9}$). Clearly, the negative signature seen in some of the events is inconsistent with the known glitch mechanisms. In this analysis, we suggest that accretion of strange nuggets with pulsars could readily give rise to microglitch events. The signature of the events depends on the energy of the strange nuggets and line of interaction.
