标题： Gravitational Waves from Spinning Compact Binaries

摘要： 快速旋转的致密双星系统（如黑洞或中子星）是引力波天文学家的主要研究目标。 由于自旋-轨道和自旋-自旋耦合的存在，这些系统的动力学非常复杂。 关于动力学的本质，已经出现了相互矛盾的结果。 在这里，我们确认尽管有相反的主张，但由广义相对论的第二后牛顿近似描述的动力学确实是混沌的。 当考虑更高阶辐射反应项引起的耗散时，混沌现象会减弱。 然而，在轨道演化末期发生的螺旋式向内运动到 plunge 的过渡阶段仍然保留了混沌行为的痕迹。 显示英文摘要

摘要： Binary systems of rapidly spinning compact objects, such as black holes or neutron stars, are prime targets for gravitational wave astronomers. The dynamics of these systems can be very complicated due to spin-orbit and spin-spin couplings. Contradictory results have been presented as to the nature of the dynamics. Here we confirm that the dynamics - as described by the second post-Newtonian approximation to general relativity - is chaotic, despite claims to the contrary. When dissipation due to higher order radiation reaction terms are included, the chaos is dampened. However, the inspiral-to-plunge transition that occurs toward the end of the orbital evolution does retain an imprint of the chaotic behaviour.
