论文摘要
我们研究了在循环黑洞的白色矮星的潮汐剥离过程中产生的电磁和重力辐射。我们超越了Chandrasekhar的思想，不仅将白色矮人本身视为量子对象，而且还以量子方式描述了产生的积聚磁盘的动态。我们将白矮星恒星建模为Bose-Fermi液滴，并使用量子流体动力方程模拟黑孔白矮人二进制二进制系统的演变。在穿过植物的时，白矮人失去了其质量的一小部分。质量落在黑洞上是强大的电磁和重力辐射的来源。在每个植物座通道时，超辐射的爆发爆发。这类似于Irwin等人最近发现的X射线源的反复发作。重力爆发主要通过在非常低的频率下发射发生。由于剥离白色矮人而形成的积聚磁盘始于一定程度，是为了不断地促进电磁和引力类型的辐射。
We investigate electromagnetic and gravitational radiation generated during the process of the tidal stripping of a white dwarf star circulating a black hole. We go beyond Chandrasekhar's ideas and not only consider a white dwarf itself as a quantum object, but also describe the dynamics of a produced accretion disk in a quantum way. We model the white dwarf star as a Bose-Fermi droplet and use the quantum hydrodynamic equations to simulate the evolution of the black hole-white dwarf binary system. While going through the periastron, the white dwarf loses a small fraction of its mass. The mass falling onto a black hole is a source of powerful electromagnetic and gravitational radiation. Bursts of ultraluminous radiation are flared at each periastron passage. This resembles the recurrent flaring of X-ray sources discovered recently by Irwin et al. Gravitational energy bursts occur mainly through emission at very low frequencies. The accretion disk, formed due to stripping of the white dwarf, starts at some point to contribute continuously to radiation of both electromagnetic and gravitational types.
