AI 中文摘要
我们提出了一类正则轴对称黑洞几何，其完全由参数$\{{\cal M},a\}$表征并具有克尔事件视界。该族在正则时空、具有可积奇点的构型以及作为极限情况的克尔解之间进行插值。其主要特征为：(i) 存在无需$a \approx {\cal M}$的准极端构型；(ii) 为从初始正则构型解析描述克尔黑洞形成提供了可能的框架。
英文摘要
We present a class of regular axisymmetric black hole geometries fully characterized by the parameters $\{{\cal M},a\}$ and possessing the Kerr event horizon. This family interpolates between regular spacetimes, configurations with integrable singularities, and the Kerr solution as a limiting case. Its main features are: (i) the existence of quasi-extremal configurations without requiring $a \approx {\cal M}$; and (ii) a possible framework toward an analytical description of Kerr black hole formation from an initially regular configuration.
