论文摘要
得出了在Kerr-Newman Black Hole的赤道平面上传播光信号的牛顿后重力时间延迟的明确形式。基于Kerr-Newman Spacetime中的无效测量，我们采用了迭代方法来计算时间延迟。如果我们从电荷中删除贡献，我们的结果将减少到Kerr黑洞的先前配方。我们用于Reissner-Nordström几何形状的时间延迟公式与以前的出版物不同[Phys。 Rev. D 69，023002（2004）]，其中最大的二阶贡献缺失了时间延迟。
The explicit form for the post-Newtonian gravitational time delay of light signals propagating on the equatorial plane of a Kerr-Newman black hole is derived. Based on the null geodesic in Kerr-Newman spacetime, we adopt the iterative method to calculate the time delay. Our result reduces to the previous formulation for Kerr black hole if we drop off the contribution from the electrical charge. Our time-delay formula for the Reissner-Nordström geometry is different from the previous publication [Phys. Rev. D 69, 023002 (2004)], in which the largest second-order contribution to the time delay is missing.
