论文摘要
使用Schwarzschild Metric和Kerr指标，可以考虑到旋转效果，从而在OJ287，Sagittarius A*-S2和H1821+643等二进制系统中获得高阶校正。进行更正是考虑运动方程的第三个根，并根据$ε\ equiv r_s/\ left（a（1-e^2）\右）$和$ε^{*} \ equiv \ left（1- \ frac {1- \ frac {2αe'} {2αe'} {cj} {cj} \ right agent avent avence avent as and a a g agent。
Higher order corrections are obtained for the perihelion precession in binary systems like OJ287, Sagittarius A*-S2 and H1821+643 using both the Schwarzschild metric and the Kerr metric to take into account the spin effect. The corrections are performed considering the third root of the motion equation and developing the expansion in terms of $ε\equiv r_s/\left(a(1-e^2)\right)$ and $ε^{*} \equiv \left(1- \frac{2 αE'}{cJ}\right) ε$.The results are compared with those obtained in a previous paper.
