相对论自旋动力学系统的数值研究

Numerical Researches on Dynamical Systems with Relativistic Spin

自旋致密双星是宇宙中的重要研究对象．其中，由恒星级致密天体绕转超大质量黑洞构成的极端质量比旋进系统（EMRIs）是美国宇航局LISA引力波探测计划的首选目标源之一，对其研究和观测不仅可以直接检验广义相对论的引力波预言，测量中央黑洞的质量和自旋，还可以揭示黑洞视界附近的基本物理性质，具有重要的物理和天体物理意义．

It is well known that spinning compact binaries are one of the most important research objects in the universe. Especially, EMRIs （extreme mass ratio inspirals） involving stellar compact objects which orbit massive black holes, are considered to be primary sources of gravitational radiation （GW） which could be detected by the space-based interferometer LISA. GW signals from EMRIs can be used to test general relativity, measure the masses and spins of central black holes and study essential physics near horizons.
