摘要:

陷阱(或 apparent)视界是追踪黑洞完整演化的关键工具。我们研究了一类由此类陷阱(或 apparent)视界在球对称动态时空中共诱导的坐标奇点,这些奇点与众所周知的与 Killing 视界相关的坐标奇点不同。特别是,我们通过 Kodama 向量场澄清了此类坐标奇点的几何结构,从而避免了非物理的 artifacts。我们进一步利用 evolving Ellis drainhole 作为分析模型,以说明该现象的关键细节。

英文摘要:

The trapping (or apparent) horizon serves as a key tool for tracing the complete evolution of black holes. We investigate a class of coordinate singularities induced by such trapping (or apparent) horizons in a spherically symmetric, dynamic spacetime, which are distinct from the well-known coordinate singularities associated with the Killing horizon. In particular, we clarify the geometric structure of this coordinate singularity by means of the Kodama vector field, thereby avoiding unphysical artifacts. We further employ the evolving Ellis drainhole as an analytical model to illustrate key details of this phenomenon.
