摘要
我们提出了一个描述旋转黑洞周围环绕通用暗物质halo的度量解。该度量解是场方程的精确解,包含具有中心密度尖刺的暗物质halo。暗物质轮廓在接近视界的半径处被截断,根据基于adiabatic不变数的分析,能量密度以及径向和切向压力在该点之后恒等于零。尖刺及其相关度量不连续性意味着时空是内在各向异性的。 resulting geometry is asymptotically flat and reduces to several well-known cases under suitable limits. In particular, it generalizes the spherically symmetric metric proposed by Cardino et al. to the case of rotating black holes. 我们讨论了模型参数的物理解释,并通过应用于几个具体引力系统来说明该度量。
