论文摘要
我们得出了在赤道平面中传播的光的分析时间延迟,并平行于移动的Kerr-Newman黑洞的速度,直至通过集成无效的测量方程,直到第二个后期后秩序。速度效应以非常紧凑的形式表示。然后,我们集中于分析校正作用对延迟二阶贡献的大小,并讨论其可能的检测。我们在第一个后期后近似中的结果与基于智障的Liénard-Wiechert潜力的Kopeikin和Schäfer的配方一致。
We derive the analytical time delay of light propagating in the equatorial plane and parallel to the velocity of a moving Kerr-Newman black hole up to the second post-Minkowskian order via integrating the null geodesic equations. The velocity effects are expressed by a very compact form. We then concentrate on analyzing the magnitudes of the correctional effects on the second-order contributions to the delay and discuss their possible detection. Our result in the first post-Minkowskian approximation is in agreement with Kopeikin and Schäfer's formulation which is based on the retarded Liénard-Wiechert potential.
