摘要：

爱因斯坦-麦克斯韦方程组的渐近平坦解的连续序列描述了普通物质的规则平衡配置可以达到黑洞极限。对于一个遥远的观察者来说，当接近极限时，时空变得越来越难以与视界外的极端Kerr-Newman黑洞的度规区分。从内部的角度来看，一个仍然规则但非渐近平坦的时空，在空间无限远处具有极端的克尔-纽曼近视界几何，在极限处形成。有趣的特殊情况是导致极端Reissner-Nordstrom黑洞的电平衡尘埃的Papapetrou-Majumdar分布序列和导致极端Kerr黑洞的旋转不带电流体体序列。

英文摘要：

Continuous sequences of asymptotically flat solutions to the Einstein-Maxwell equations describing regular equilibrium configurations of ordinary matter can reach a black hole limit. For a distant observer, the spacetime becomes more and more indistinguishable from the metric of an extreme Kerr-Newman black hole outside the horizon when approaching the limit. From an internal perspective, a still regular but non-asymptotically flat spacetime with the extreme Kerr-Newman near-horizon geometry at spatial infinity forms at the limit. Interesting special cases are sequences of Papapetrou-Majumdar distributions of electrically counterpoised dust leading to extreme Reissner-Nordstrom black holes and sequences of rotating uncharged fluid bodies leading to extreme Kerr black holes.
