论文摘要
我们通过无效的测量学作为中央力系统研究光学指标，推断相关的binet方程，并将分析应用于带有或没有球形对称性的爱因斯坦方程的某些溶液。 Schwarzschild-Tangherlini（ST）度量的弱透镜状态中挠度角的一般公式被得出。此外，我们获得了一个新的弱透镜公式，用于在Kerr Black Hole（BH）的赤道平面上的偏转角。我们还通过考虑Tomimatsu-Sato（TS）度量所描述的引力物体来探索光的弯曲。
We study optical metrics via null geodesics as a central force system, deduce the related Binet equation and apply the analysis to certain solutions of Einstein's equations with and without spherical symmetry. A general formula for the deflection angle in the weak lensing regime for the Schwarzschild-Tangherlini (ST) metric is derived. In addition, we obtain a new weak lensing formula for the deflection angle on the equatorial plane of a Kerr black hole (BH). We also explore the bending of light by considering the gravitational objects described by the Tomimatsu-Sato (TS) metric.
