论文摘要
这项工作探讨了是否可以使用当前的第二代和未来的第三代GW检测器来检测中子恒星（NS）山脉的重力波（GWS）。特别是，我们关注的是在NS故障之后立即形成瞬态山脉的情况。在小故障中，A NS的自旋频率突然增加，然后经常呈指数式恢复回到毛刺之前的旋转频率。如果由于短暂山的山脉而将恢复归因于额外的扭矩，我们发现该山的GWS在设计敏感性时可以略微检测到高级LIGO，并且很可能是Einstein望远镜等第三代探测器可检测到的。使用此模型，我们能够在可观察的情况下找到GW振幅及其持续时间的分析表达式。
This work explores whether gravitational waves (GWs) from neutron star (NS) mountains can be detected with current 2nd-generation and future 3rd-generation GW detectors. In particular, we focus on a scenario where transient mountains are formed immediately after a NS glitch. In a glitch, a NS's spin frequency abruptly increases and then often exponentially recovers back to, but never quite reaches, the spin frequency prior to the glitch. If the recovery is ascribed to an additional torque due to a transient mountain, we find that GWs from that mountain are marginally-detectable with Advanced LIGO at design sensitivity and is very likely to be detectable for 3rd-generation detectors such as the Einstein Telescope. Using this model, we are able to find analytical expressions for the GW amplitude and its duration in terms of observables.
