论文摘要
重新探讨了Schwarzschild Geodesics的理论。根据Weierstrass和Biermann的结果,我们得出了一个公式,该公式用Weierstrass椭圆函数来描述所有非径向,时型和无效轨迹。非常值得注意的是,即使它通过转折点,一个公式也适用于整个地质轨迹。使用此公式,我们得出沿着测量的适当和坐标时间的表达式。
The theory of Schwarzschild geodesics is revisited. Basing on a result by Weierstrass and Biermann, we derive a formula describing all non radial, timelike and null trajectories in terms of Weierstrass elliptic functions. Quite remarkably, a single formula works for an entire geodesic trajectory, even if it passes through turning points. Using this formula, we derive expressions for the proper and coordinate time along the geodesic.
