广义黑洞

Generalized black diholes

I. Cabrera-Munguia, Claus Lämmerzahl, L. A. López, Alfredo Macías

摘要:

构造了一个描述具有相反电磁荷的同向反旋黑洞组成的双星系统的5参数精确解。角动量参数的添加到静态恩帕兰-特奥双孔模型引入磁荷到这个两体系统。该解可以看作是描述广义双荷黑洞的一个扩展模型。我们推导出视界半长参数$σ$作为Komar参数的函数的显式函数形式:Komar质量$M$,电/磁荷$Q_{E }/ Q_{B}$,角动量$J$和坐标距离$R$,其中参数$(M, J, Q_E, Q_B, R)$表征系统的上部成分,而$(M, -J, -Q_E, -Q_B, R)$与下部成分相关。磁荷的加入增强了标准的斯马尔质量公式,以考虑它们对质量的贡献。作为特殊情况,该解决方案包含文献中已经讨论过的两种解决方案。

英文摘要:

A 5-parametric exact solution, describing a binary system composed of identical counter-rotating black holes endowed with opposite electromagnetic charges, is constructed. The addition of the angular momentum parameter to the static Emparan-Teo dihole model introduces magnetic charges into this two-body system. The solution can be considered as an extended model for describing generalized black diholes as dyons. We derive the explicit functional form of the horizon half-length parameter $σ$ as a function of the Komar parameters: Komar mass $M$, electric/magnetic charge $Q_{E }/ Q_{B}$, angular momentum $J$, and a coordinate distance $R$, where the parameters $(M, J, Q_E, Q_B, R)$ characterize the upper constituent of the system, while $(M, -J, -Q_E, -Q_B, R)$ are associated with the lower one. The addition of magnetic charges enhances the standard Smarr mass formula in order to take into account their contribution to the mass. The solution contains, as particular cases, two solutions already discussed in the literature.
