作为静电真空时空源的反向旋转理想流体盘

Counterrotating perfect fluid discs as sources of electrovacuum static spacetimes

Gonzalo García-Reyes, Guillermo A. González

摘要:

本文提出用反向旋转的理想流体圆盘来解释某些电真空时空。解释是由一个“反问题”的方法来获得已知的静态解的爱因斯坦-麦克斯韦方程组盘源。为了做这样的解释,提出了一个详细的研究的通用电真空静态轴对称相对论薄盘与非零径向压力的反转模型(CRM)。四个简单的家庭的模型的基础上Chazy-Curzon型,Zipoy-Voorhees型,Bonnor-Sackfield型,带电和磁化的Darmois电真空度规的反向旋转带电盘被认为是我们得到一些光盘与CRM表现良好。

英文摘要:

The interpretation of some electrovacuum spacetimes in terms of counterrotating perfect fluid discs is presented. The interpretation is mades by means of an "inverse problem" approach used to obtain disc sources of known static solutions of the Einstein-Maxwell equations. In order to do such interpretation, a detailed study is presented of the counterrotating model (CRM) for generic electrovacuum static axially symmetric relativistic thin discs with nonzero radial pressure. Four simple families of models of counterrotating charged discs based on Chazy-Curzon-type, Zipoy-Voorhees-type, Bonnor-Sackfield-type, and charged and magnetized Darmois electrovacuum metrics are considered where we obtain some discs with a CRM well behaved.
