Title: 脉冲星作为韦伯引力波探测器

Abstract: A gravitational wave passing through a pulsar will lead to a variation in the moment of inertia of the pulsar affecting its rotation. This will affect the extremely accurately measured spin rate of the pulsar as well as its pulse profile (due to induced wobbling depending on the source direction). The effect will be most pronounced at resonance and should be detectable by accurate observations of the pulsar signal. The pulsar, in this sense, acts as a remotely stationed Weber detector of gravitational waves whose signal can be monitored on earth. With possible gravitational wave sources spread around in the universe, pulsars in their neighborhoods can provide us a family of \textit{remote} detectors all of which can be monitored on earth. Even if GW are detected directly by earth based conventional detectors, such pulsar detectors can provide additional information for accurate determination of the source location. This can be of crucial importance for sources which do not emit any other form of radiation such as black hole mergers. Show Chinese abstract

Abstract: 通过脉冲星的引力波会导致脉冲星的转动惯量发生变化，从而影响其旋转。 这也将影响脉冲星极其精确测量的自转速率以及其脉冲轮廓（由于根据源方向引起的抖动）。 在共振时，这种效应最为明显，并可以通过对脉冲星信号的精确观测进行检测。 从这个意义上说，脉冲星充当了一个远程安置的引力波韦伯探测器，其信号可以在地球上进行监测。 随着可能的引力波源散布在宇宙中，它们周围的脉冲星可以为我们提供一组 \textit{远程} 探测器，所有这些都可以在地球上进行监测。 即使引力波被基于地球的传统探测器直接检测到，这样的脉冲星探测器也可以提供额外的信息，用于准确确定源的位置。 这对于不发射任何其他形式辐射的源，如黑洞合并，可能具有关键的重要性。
