论文摘要
我们研究颗粒与标量场（SF）耦合的影响对稳定的圆形轨道（SCO）的分布，围绕众所周知的Fisher-Janis-Janis-Newman-Winicour溶液描述的裸奇异性。分析了粒子 - -SF相互作用的幂律和指数模型。重点放在非连接的SCO分布上。我们表明，颗粒和SF之间的耦合基本上使SCO分布的拓扑复杂化。特别是，它可能导致新的非重叠的SCO区域，这些区域由不稳定的轨道和/或不存在圆形轨道的区域隔开。
We study effects of the particles coupling with scalar field (SF) on the distribution of stable circular orbits (SCO) around the naked singularity described by the well-known Fisher-Janis-Newman-Winicour solution. The power-law and exponential models of the particle--SF interaction are analyzed. The focus is on the non-connected SCO distributions. We show that coupling between particles and SF can essentially complicate the topology of the SCO distributions. In particular, it can lead to new non-overlapping SCO regions, which are separated by unstable orbits and/or by regions where the circular orbits do not exist.
