论文摘要
我们研究了外部物质的静态和中性分布如何扭曲5维静态黑环。我们从背景度量函数和失真场上获得了扭曲的度量标准的一般表达，并找到了后者的多极扩展。我们证明，可以调整这些外部来源的重力场，以去除未发生的黑环溶液的圆锥形奇异性。我们分析了扭曲的黑环的特性，以针对偶极子和四极杆变形的特定情况。
We investigate how a static and neutral distribution of external matter distorts a 5-dimensional static black ring. We obtain a general expression for the distorted metric in terms of the background metric functions and the distortion fields, and find a multipole expansion for the latter. We demonstrate that the gravitational field of these external sources can be adjusted to remove the conical singularity of the undistorted black ring solution. We analyze properties of the distorted black ring for the specific cases of dipole and quadrupole distortions.
