旋转线轨道黑洞不违反弱宇宙监督猜想

Weak cosmic censorship conjecture is not violated for a rotating linear dilaton black hole

摘要:

本文从两种不同的方法研究了黑洞上旋转线性粒子的弱宇宙监督猜想(WCCC)的有效性。用经典的进入试验粒子方法,得到了与Wald最近提出的新的Gedanken实验相同的结果。我们发现,即使对于这种旋转的线性轨道的黑洞的Iyer-Wald形式仍然是有效的。通过对这两种方法的比较,我们发现,在一阶以下的两种情况下,得到的结果是相同的。接近极端的黑洞可以超旋,而极端的黑洞不能超旋。当我们考虑到二阶修正时,Iyer-Wald方法表明,即使对于接近极值的黑洞,WCCC也能得到很好的保护.这些结果表明,弱宇宙监督猜想仍然是有效的使用进入测试粒子的方法,直到二阶修改。

英文摘要:

In this paper, we investigate the validity of the weak cosmic censorship conjecture(WCCC) for a rotating linear dilaton black hole from two different methods. By using the classsical ingoing test particle method, we obtain the same results as given in the new version of gedanken experiment recently proposed by Wald. We find that even for this rotating linear dilaton black hole the Iyer-Wald formalism is still functioning. By comparing these two methods, we find that the same result will be obtained in both cases up to first order. The nearly extremal black hole can be overspun, while the extremal one cannot be overspun. When we include the second order modification into consideration, the Iyer-Wald method show that even for the nearly extremal black hole, the WCCC is well protected. These results imply that weak cosmic censorship conjecture is still valid using the ingoing test particle method up to second order modification.
