论文摘要
将黑洞二进制文件与小质量比率(SMR)合并为对称质量比率(后绝热膨胀)的动力学。使用数值相对论模拟,我们计算了本系列中的前三个术语,用于半圆周非旋转二进制文件。我们恢复了SMR扰动理论预测的主要术语,并获得了1个绝热项的强大预测。发现2杆 - 绝热项很小,表明即使对于几乎可比的质量二进制,1PA近似也可能非常准确。我们还估计了SMR和Newtonian Series的适用性范围,用于非旋转,准圆的灵感。
The dynamics of merging black hole binaries with small mass-ratios (SMR) can be expressed as a series in the symmetric mass-ratio, the post-adiabatic expansion. Using numerical relativity simulations, we compute the first three terms in this series for quasicircular non-spinning binaries. We recover the leading term predicted by SMR perturbation theory, and obtain a robust prediction of the 1-post-adiabatic term. The 2-post-adiabatic term is found to be small, indicating that the 1PA approximation may be quite accurate even for nearly comparable mass binaries. We also estimate the range of applicability for SMR and post-Newtonian series for non-spinning, quasi-circular inspirals.
