In this paper we investigate the motion of electrically charged test particle orbiting electrically charged higher dimensional Reissner–Nordström black holes. Specifically, we analyze the radii of the photonsphere and shadow, the innermost stable circular orbits, and the capture cross section of charged particles across various dimensions of spacetime. Our study in the capture of the charged particle encompasses both relativistic and non-relativistic regimes. Our results reveal that the electromagnetic interaction between the black hole and the charged particle significantly influences the radii of all characteristic orbits and the capture cross sections, with the electromagnetic attraction (repulsion) between them leading to an increase (decrease) in these parameters.

赖斯纳-诺德斯特伦-坦格尔利尼时空中的带电粒子动力学

在本文中，我们研究了带电测试粒子绕带电高维赖斯纳-诺德斯特伦黑洞运行的运动。具体来说，我们分析了光子球和阴影的半径、最里面的稳定圆形轨道以及跨时空各个维度的带电粒子的捕获截面。我们对带电粒子捕获的研究涵盖相对论和非相对论领域。我们的结果表明，黑洞与带电粒子之间的电磁相互作用显着影响所有特征轨道的半径和捕获截面，它们之间的电磁吸引力（斥力）导致这些参数的增加（减少）。
