论文摘要

我们在完全相对论中进行积聚,等质二元黑洞的磁性水力动力学模拟,重点是自旋和微型风格对吸积率和po散发光度变化的影响。我们报告微型质量,质量积聚率和亮度的微型风险和周期性的结构。吸积率表现出与我们研究的所有系统中二进制的轨道频率相关的准周期行为,但是该调制的幅度取决于持续的微型企业的存在。特别是,发现产生持续微型的系统对质量积聚率的调制较弱,表明微型企业可以将物质的流入时间增加到黑洞中,并抑制了准周期性的行为。这一发现对较大的分离有潜在的后果,在较大的分离中,微型风险可能会大得多,并且可能会大大降低周期性。

We perform magnetohydrodynamic simulations of accreting, equal-mass binary black holes in full general relativity focusing on the effect of spin and minidisks on the accretion rate and Poynting luminosity variability. We report on the structure of the minidisks and periodicities in the mass of the minidisks, mass accretion rates, and Poynting luminosity. The accretion rate exhibits a quasi-periodic behavior related to the orbital frequency of the binary in all systems that we study, but the amplitude of this modulation is dependent on the existence of persistent minidisks. In particular, systems that are found to produce persistent minidisks have a much weaker modulation of the mass accretion rate, indicating that minidisks can increase the inflow time of matter onto the black holes, and dampen out the quasi-periodic behavior. This finding has potential consequences for binaries at greater separations where minidisks can be much larger and may dampen out the periodicities significantly.
