Dynamics of Compact, Extended Celestial Bodies in Strong Gravitational Fields

天体的质量只有自身质量的一小部分 这是由于它们内部的引力束缚， 天体的大小是有限的（而不是点， 身体）。 这样的物体经历着它们最具启示性的运动 当位于接近黑色的强引力场时 孔或其他高度紧凑的物体。 运动方程 在强重力环境中， 将从第一原理计算， 相对论和替代理论。 摄动 理论将被应用于精确的强场 Schwarzschild环境，而不是使用 对真空Minkowski环境的扰动 对运动问题的经典研究。 直接应用 这些计算的结果可以用来 解读现代射电望远镜的观测结果 观测的恒星，以及不久的将来的努力，以检测 并理解来自宇宙的引力波信号。

Celestial bodies possess a fraction of their own mass which results from their internal gravitational binding, and celestial bodies have finite size (rather than being point- bodies). Such bodies undergo their most revealing motions when located in the strong gravitational fields close to black holes or other highly compact bodies. The equations of motion of such bodies when located in the strong gravity environment will be calculated from first principles, both in general relativity theory and in alternative theories. Perturbation theory will be applied to the exact, strong field Schwarzschild environment, rather than working with the perturbations to the empty space Minkowski environment of the classic studies of this problem of motion. Direct application of the results of these calculations can be made to interpreting the results of present-day radio telescope observations of pulsars, and to near-future efforts to detect and understand gravity wave signals from the cosmos.
