Hangup Kicks:利用黑洞双星的部分自旋/轨道排列获得更大的粒子

Hangup Kicks: Still Larger Recoils by Partial Spin/Orbit Alignment of Black-Hole Binaries

Carlos O. Lousto, Yosef Zlochower

摘要:

我们重新审视的情况下获得的引力辐射反冲的最后残余的黑洞,通过研究一组配置,有组件的自旋都与轨道角动量和轨道平面。我们进行了一系列的42个新的完整的数值模拟等质量和等自旋星等的双星。我们扩展了以前的反冲拟合公式,包括非线性项的自旋,并成功地包括新的和已知的结果。新的预测的最大速度接近5000公里/秒的自旋部分对准轨道角动量,这导致了一个重要的增加的概率大反冲在一般的天体物理合并。我们发现不可忽略的概率反冲几千公里/秒的吸积对准双星。

英文摘要:

We revisit the scenario of the gravitational radiation recoil acquired by the final remnant of a black-hole-binary merger by studying a set of configurations that have components of the spin both aligned with the orbital angular momentum and in the orbital plane. We perform a series of 42 new full numerical simulations for equal-mass and equal-spin-magnitude binaries. We extend previous recoil fitting formulas to include nonlinear terms in the spins and successfully include both the new and known results. The new predicted maximum velocity approaches 5000km/s for spins partially aligned with the orbital angular momentum, which leads to an important increase of the probabilities of large recoils in generic astrophysical mergers. We find non-negligible probabilities for recoils of several thousand km/s from accretion-aligned binaries.
