D. Pugliese, Z. Stuchlik

摘要:

我们考虑的聚集体的错位,压力支持环面轨道史瓦西黑洞。引入了一个引导函数,调节中央静态吸引子周围的圆环分布,它使模型的错位圆环聚集作为一个单一的轨道(宏-)配置。我们首先分析纯流体动力学完美流体环的主导功能。随后,针对环形磁场的存在修改函数。我们研究的约束环碰撞出现和不稳定的团聚体的不对准环面一般的相对倾角。讨论了双峰高频准周期振荡(HF-QPO)与凝聚体内环结构有关的可能性。系统的离散几何形状与HF-QPO有关,考虑与环形内边缘相关的几个振荡测地线模型。我们还研究了环面几何厚度对振荡现象的可能影响。

英文摘要:

We consider agglomerates of misaligned, pressure supported tori orbiting a Schwarzschild black hole. A leading function is introduced, regulating the toroids distribution around the central static attractor-it enables to model the misaligned tori aggregate as a single orbiting (macro--)configuration. We first analyze the leading function for purely hydrodynamical perfect fluid toroids. Later, the function is modified for presence of a toroidal magnetic field. We study the constraints on the tori collision emergence and the instability of the agglomerates of misaligned tori with general relative inclination angles. We discuss the possibility that the twin peak high-frequency quasi-periodic oscillations (HF-QPOs) could be related to the agglomerate inner ringed structure. The discrete geometry of the system is related to HF-QPOs considering several oscillation geodesic models associated to the toroids inner edges. We also study possible effect of the tori geometrical thickness on the oscillatory phenomena.
