Kerr时空中沿一般束缚测地线平行输运的解析解

Analytic solutions for parallel transport along generic bound geodesics in Kerr spacetime

Maarten van de Meent

摘要:

我们提供了解析封闭形式的解决方案的平行运输沿约束测地线克尔时空。这可以被认为是一个旋转的黑洞在极端质量比内旋运动的最低阶近似。作为我们的新发现的表达式的有用性的说明,我们范围出的自旋自旋共振准圆形EMRI的位置。所有的解决方案作为米诺时间的函数,这有利于解耦的运动方程。为了帮助物理解释,我们还提供了一个解析表达式的适当的时间沿测地线作为米诺时间的函数。

英文摘要:

We provide analytical closed form solutions for the parallel transport along a bound geodesic in Kerr spacetime. This can be considered the lowest order approximation for the motion a spinning black hole in an extreme mass-ratio inspiral. As an illustration of the usefulness of our new found expressions we scope out the locations of spin-spin resonances in quasi-circular EMRIs. All solutions are given as functions of Mino time, which facilitates the decoupling of the equations of motion. To help physical interpretation, we also provide an analytical expression for the proper time along a geodesic as a function of Mino time.
