极端和中等质量比吸气的重力波形。III:自旋轨道耦合的再认识

Self-force gravitational waveforms for extreme and intermediate mass ratio inspirals. III: Spin-orbit coupling revisited

Lior M. Burko, Gaurav Khanna

摘要:

将一阶、二阶耗散自力和一阶保守自力与自旋轨道耦合作用一起应用于史瓦西黑洞时空中测试质量的准圆运动,得到了极端或中等质量比的结果.由于自作用力的引力波形的部分移相(在该顺序是独立的系统的质量比)进行了比较与自旋轨道耦合。我们发现,准确的波形参数估计需要包括这两个影响。具体地说,我们找到一个特定的值的自旋参数,使自旋轨道效应抵消了自作用力的影响的波形。因此,排除与质量比无关的失相效应可能导致系统参数估计中的非微扰误差。

英文摘要:

The first- and second-order dissipative self force and the first order conservative self force are applied together with spin-orbit coupling to the quasi-circular motion of a test mass in the spacetime of a Schwarzschild black hole, for extreme or intermediate mass ratios. The partial dephasing of the gravitational waveform (at the order that is independent of the system's mass ratio) due to the self force is compared with that of spin-orbit coupling. We find that accurate waveforms for parameter estimation need to include both effects. Specifically, we find a particular value for the spin parameter such that the spin-orbit effect cancels out the self-force effect on the waveform. Exclusion of dephasing effects that are independent of the mass ratio therefore might lead to a non-perturbative error in the estimation of the system's parameters.
