规则旋转黑洞与弱能量条件

Regular rotating black holes and the weak energy condition

J. C. S. Neves, Alberto Saa

摘要:

我们在这里重温最近的定期旋转黑洞的工作。我们引入了一个新的质量函数,推广了常用的Barclay和Hayward质量函数,并扩展了最近提出的解决方案,以适应宇宙学常数$Λ$。我们讨论的因果结构(视野)和新提出的解决方案的遍历的一些方面。我们还表明,与球对称的情况下,黑洞的旋转将不可避免地导致违反弱能量条件的任何物理合理的选择的质量函数,加强的想法克尔黑洞的内部区域的描述是更具挑战性的比在史瓦西的情况下。

英文摘要:

We revisit here a recent work on regular rotating black holes. We introduce a new mass function generalizing the commonly used Bardeen and Hayward mass functions and extend the recently proposed solutions in order to accommodate a cosmological constant $Λ$. We discuss some aspects of the causal structure (horizons) and the ergospheres of the new proposed solutions. We also show that, in contrast with the spherically symmetrical case, the black hole rotation will unavoidably lead to the violation of the weak energy condition for any physically reasonable choice of the mass function, reinforcing the idea the description of the interior region of a Kerr black hole is much more challenging than in the Schwarzschild case.
