Kerr参数任意取值时Kerr时空吸积过程的数值模拟

Numerical simulations of the accretion process in Kerr space-times with arbitrary value of the Kerr parameter

Cosimo Bambi

摘要:

根据宇宙审查猜想,所有由坍缩物质产生的奇点都必须隐藏在一个事件视界后面。在四维广义相对论中,这意味着坍缩的最终产物是一个克尔-纽曼黑洞。在这里,我考虑了宇宙审查猜想被违反的可能性。本文给出了Kerr黑洞(具有事件视界的物体)和Kerr超旋子(没有事件视界的快速旋转物体)吸积过程的数值模拟结果。这是一个初步的研究,探讨如何宇宙审查猜想可以通过天体物理观测来检验。

英文摘要:

According to the Cosmic Censorship Conjecture, all the singularities produced by the collapsing matter must be hidden behind an event horizon. In 4D general relativity, this implies that the final product of the collapse is a Kerr-Newman black hole. Here I consider the possibility that the Cosmic Censorship Conjecture can be violated. I present the results of some numerical simulations of the accretion process onto Kerr black holes (objects with event horizon) and Kerr super-spinars (fast-rotating objects without event horizon). This is a preliminary study to investigate how the Cosmic Censorship Conjecture can be tested by astrophysical observations.
