Global embeddings and hydrodynamic properties of Kerr black hole

Soon-Tae Hong

摘要:

在旋转Kerr黑洞存在的情况下,研究了有质量粒子和无质量光子的流体动力学,建立了旋转Kerr黑洞周围有质量粒子和光子的数密度、压强和内能密度之间的关系,并研究了黑洞的吸积.在Kerr黑洞的赤道面上,我们研究了大质量粒子和光子围绕黑洞的束缚轨道,得到了它们的径向、方位角和岁差频率。利用这些频率,我们研究了黑洞GRO~ J 1655 -40和4U~1543-47,明确地得到了理想流体流中大质量粒子的径向、方位角和进动频率。接下来我们考虑Kerr弯曲时空中超新星SN 1979 C、SN 1987 A和SN 2213-1745周围半径为$1.0~ly$的稳定圆形轨道中的大质量粒子,以及潜在的超大质量史瓦西黑洞M87、NGC 3115、NGC 4594、NGC 3377、NGC 4258、M31、M32和银河系中心周围的大质量粒子。估计了它们的径向频率和方位频率,结果与没有进动运动时的结果相同。根据光子轨道的碰撞参量讨论了光子的不稳定轨道。最后,在Kerr黑洞的赤道面上,我们构造了旋转Kerr黑洞事件视界内外具有(9+3)维的整体平坦嵌入结构.此外,在平面上,我们研究了Kerr时空的弯曲积。

英文摘要:

In the presence of a rotating Kerr black hole, we investigate hydrodynamics of the massive particles and massless photons, to construct relations among number density, pressure and internal energy density of the massive particles and photons around the rotating Kerr black hole and to study an accretion onto the black hole. On equatorial plane of the Kerr black hole, we investigate the bound orbits of the massive particles and photons around the black hole to produce their radial, azimuthal and precession frequencies. With these frequencies we study the black holes GRO~J1655-40 and 4U~1543-47, to explicitly obtain the radial, azimuthal and precession frequencies of the massive particles in the flow of perfect fluid. We next consider the massive particles in the stable circular orbit of radius of $1.0~ly$ around the supernovas SN 1979C, SN 1987A and SN 2213-1745 in the Kerr curved spacetime, and around the potential supermassive Schwarzschild black holes M87, NGC 3115, NGC 4594, NGC 3377, NGC 4258, M31, M32 and Galatic center, to estimate their radial and azimuthal frequencies, which are shown to be the same results as those in no precession motion. The photon unstable orbit is also discussed in terms of the impact parameter of the photon trajectory. Finally, on the equatorial plane of the Kerr black hole, we construct the global flat embedding structures possessing (9+3) dimensionalities outside and inside the event horizon of the rotating Kerr black hole. Moreover, on the plane we investigate the warp products of the Kerr spacetime.
