Spinning neutron stars, when observed as pulsars, are seen to undergo occasional spin-up events known as glitches. Despite several decades of study, the physical mechanisms responsible for glitches are still not well understood, but probably involve an interplay between the star’s outer elastic crust, and the superfluid and superconducting core that lies within. Glitches will be accompanied by some level of gravitational wave emission. In this article, we review proposed models that link gravitational wave emission to glitches, exploring both short duration burst-like emission, and longer-lived signals. We illustrate how detections (and in some cases, non-detections) of gravitational signals probe both the glitch mechanism, and, by extension, the behaviour of matter at high densities.

当将旋转中子星作为脉冲星观察时，人们发现它偶尔会经历称为毛刺的旋转事件。尽管经过了几十年的研究，造成故障的物理机制仍然没有得到很好的理解，但可能涉及恒星外部弹性地壳与内部超流体和超导核心之间的相互作用。故障将伴随一定程度的引力波发射。在本文中，我们回顾了将引力波发射与毛刺联系起来的提出的模型，探索了短持续时间的突发式发射和寿命较长的信号。我们说明了引力信号的检测（在某些情况下，未检测到）如何探测故障机制，并进一步探测高密度物质的行为。
