摘要

时空奇点无法直接观测到,因为它被事件穹界所覆盖。裸奇点可能在没有事件穹界的情况下因引力坍缩而形成。因此,宇宙审查猜想需要提前确定。最近,Joshi 等人发现了一种裸奇点方案(称为 JMN 裸奇点),它是由大质量物质云的动态引力坍缩产生的。由于需要进行一些研究来了解更多有助于检验广义相对论中宇宙审查猜想的额外特征,因此我们认为研究裸奇点对大质量粒子的偏转是很有意义的。在本研究中,我们将研究裸奇点附近的大质量粒子路径和偏转角。为了得到偏转角,我们采用了高斯-波奈技术和林德勒-伊沙克方法。我们将对两种方法的结果进行详细比较。

Gravitational deflection of massive body around naked singularity

Spacetime singularity is not observed directly as it is covered by event horizon. Naked singularities may be formed due to gravitational collapse without an event horizon. Therefore, cosmic censorship conjecture entails advanced ascertainment. Recently, Joshi et al. have discovered a naked singularity solution (known as JMN naked singularity), which emerges from the dynamical gravitational collapse of a massive matter cloud. Since several studies are needed to know more extra characteristics that may help to test cosmic censorship conjecture in general relativity, therefore, we thought it is pertinent to study the deflection of massive particles by the naked singularity. We shall examine massive particles paths and deflection angles near naked singularities in this research. To get the deflection angle, we employ the Gauss-Bonet technique and the Rindler-Ishak method. The results of the two procedures are compared in detail.

期刊介绍: Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
