对引力反冲的进一步认识

Further insight into gravitational recoil

Carlos O. Lousto, Yosef Zlochower

摘要:

我们测试的准确性,我们最近提出的经验公式来模拟反冲速度赋予合并剩余的旋转,不等质量的黑洞双星。我们研究了三个家庭的黑洞二元配置,所有的质量比q=3/8(最大化不等质量的贡献踢)和自旋对齐(或计数器对齐)与轨道角动量,两个自旋配置选择,以尽量减少自旋诱导的切向和径向加速度的轨迹分别,和第三个家庭的轨迹显着改变自旋轨道耦合。我们发现前两个家庭的测量和预测的反冲速度之间的良好协议,第三个合理的协议。我们还重新审视了我们原来的通用二元配置,导致发现了极大的自旋驱动的反冲速度,并启发了我们的经验公式,并找到合理的预测和测量的反冲速度之间的协议。

英文摘要:

We test the accuracy of our recently proposed empirical formula to model the recoil velocity imparted to the merger remnant of spinning, unequal-mass black-hole binaries. We study three families of black-hole binary configurations, all with mass ratio q=3/8 (to maximize the unequal-mass contribution to the kick) and spins aligned (or counter aligned) with the orbital angular momentum, two with spin configurations chosen to minimize the spin-induced tangential and radial accelerations of the trajectories respectively, and a third family where the trajectories are significantly altered by spin-orbit coupling. We find good agreement between the measured and predicted recoil velocities for the first two families, and reasonable agreement for the third. We also re-examine our original generic binary configuration that led to the discovery of extremely large spin-driven recoil velocities and inspired our empirical formula, and find reasonable agreement between the predicted and measured recoil speeds.
