黑洞双星的内旋和轨道优势

Black hole binary inspiral and trajectory dominance

Richard H. Price, Gaurav Khanna, Scott A. Hughes

摘要:

在黑洞双星的螺旋、俯冲和合并过程中所发射的引力波携带线性动量。这导致了对最终合并的黑洞的天体物理学重要的反冲,一种可以将它从星系核中弹出的"反冲“。在以前的论文中,我们表明,令人费解的部分抵消早期的踢一个后期的反踢,并依赖于黑洞自旋的取消,可以理解的线性动量波形的现象。在这里,我们将这种现象与其根本原因联系起来,即螺旋轨道的自旋依赖性。这一见解表明,暴跌的细节可以更广泛地理解,重点是螺旋轨迹。

英文摘要:

Gravitational waves emitted during the inspiral, plunge and merger of a black hole binary carry linear momentum. This results in an astrophysically important recoil to the final merged black hole, a ``kick'' that can eject it from the nucleus of a galaxy. In a previous paper we showed that the puzzling partial cancellation of an early kick by a late antikick, and the dependence of the cancellation on black hole spin, can be understood from the phenomenology of the linear momentum waveforms. Here we connect that phenomenology to its underlying cause, the spin-dependence of the inspiral trajectories. This insight suggests that the details of plunge can be understood more broadly with a focus on inspiral trajectories.
