论文摘要
在本文中,我们将重力解耦方法应用于动力系统,以获取一种可以描述毛茸茸的动态黑洞的新型解决方案。我们考虑三个脱钩的情况。当质量函数仅是空间坐标$ r $的函数时,第一个是最简单和众所周知的。第二种情况是当质量函数取决于时间$ v $时,Vaidya时空情况。第三种情况代表了这两种情况的概括:质量功能是$ r $和$ v $的功能。我们还计算所有三种情况的明显范围和奇异位置。
In this paper we apply the gravitational decoupling method for dynamical systems in order to obtain a new type of solution which can describe a hairy dynamical black hole. We consider three cases of decoupling. The first one is the simplest and well-known when the mass function is the function only of space coordinate $r$. The second case is Vaidya spacetime case when the mass function depends on time $v$ . And the third case represents the generalization of these two cases: the mass function is the function of both $r$ and $v$. We also calculate the apparent horizon and singularity location for all three cases.
