广义Vaidya度量的双零表示

Double null formulation of the general Vaidya metric

Cecilia Chirenti, Alberto Saa

摘要:

本文给出了在双零坐标系下,用一般的带宇宙学常数λ的带电Vaidya度规描述的具有变化质量m(v)和/或电荷q(v)的非稳态球对称n维带电黑洞的场方程.这种制定的度量已被证明是特别有用的微扰研究,它被用于最近的一些作品。本文还讨论了与黑洞的视视界和事件视界有关的一些问题。

英文摘要:

We present here the field equations describing a non-stationary spherically symmetric n-dimensional charged black hole with varying mass m(v) and/or electric charge q(v), described by a generic charged Vaidya metric with cosmological constant Lambda in double null coordinates. This formulation of the metric has been shown to be particularly useful for perturbative studies and it was used in some recent works. Here we also discuss some issues related to the apparent and event horizons of the black hole.
