在弱场近似下,可以求解爱因斯坦场方程组,从而得到引力波的预测。在证明引力辐射依赖于变化的四极矩之后,本章描述了引力波的产生、传播和探测。它包括对重力速度、探测器、紧凑双星系统的“啁啾”波形以及天体物理源的性质的讨论。
In the weak field approximation, the Einstein field equations can be solved, and lead to the prediction of gravitational waves. After showing that gravitational radiation depends on changing quadrupole moments, this chapter describes the production, propagation, and detection of gravitational waves. It includes discussions of the speed of gravity, detectors, the “chirp” waveform for a compact binary system, and the nature of astrophysical sources.
