2PN近似下光在单运动粒子场中的传播:I.初值问题

Light propagation in 2PN approximation in the field of one moving monopole: I. Initial value problem

Sven Zschocke

摘要:

本文在后牛顿第二近似下研究了光在任意运动物体的引力场中的传播。发现光的轨迹依赖于物体的加速度。为了得到具有无量纲参数的良好定义的对数函数,其中一些加速度项是重要的,而所有其他加速度项在时间延迟测量的皮秒级精度上是可以忽略的。确定了观测量总光偏转和时间延迟的表达式。

英文摘要:

In this investigation the light propagation in the gravitational field of one arbitrarily moving body with monopole structure is considered in the second post-Newtonian approximation. It is found that the light trajectory depends on the acceleration of the body. Some of these acceleration terms are important in order to get well-defined logarithmic functions with dimensionless arguments, while all the other acceleration terms are negligible on the pico-second level of accuracy in time-delay measurements. The expressions of the observables total light deflection and time delay are determined.
