论文摘要
我们考虑了从球形对称性出发的某些含义，即描述黑洞模仿者真空爱因斯坦方程的静态解。特别是，我们研究了质量四极矩的存在如何影响测试颗粒的碰撞能量。我们表明，这种异国情调紧凑源的碰撞过程具有非消失的质量四极力矩可能与黑洞附近的碰撞过程可能显着不同。
We consider some implications of the departure from spherical symmetry for static solutions of the vacuum Einstein's equations describing black hole mimickers. In particular, we investigate how the presence of mass quadrupole moment affects the collision energy of test particles. We show that collision processes in the vicinity of such exotic compact sources with non vanishing mass quadrupole moment may be significantly different from those in the vicinity of black holes.
