Abstract

We propose a new framework for spherical charged compact objects admitting conformal motion in five-dimensional spacetime. The outer spacetime is considered as Reissner-Nordström to obtain matching conditions. The behavior of model characteristics like stress, pressure, and surface tension for the specific density profile is investigated by using Einstein's Maxwell field equations in a five-dimensional framework. For the proposed solution, all physical parameters behave very well even for variations in electric charge parameters. The existence of charged compact stars is also predicted by this study.

摘要

我们提出了一个新的框架，用于描述在五维时空中具有共形运动的球形带电紧致物体。外部时空被视为 Reissner-Nordström 时空，以获得匹配条件。通过在五维框架中使用爱因斯坦的麦克斯韦场方程，研究了模型特征（如应力、压力和表面张力）对于特定密度分布的行为。对于所提出的解，所有物理参数的行为都非常好，即使在电荷参数变化的情况下也是如此。这项研究还预测了带电致密星的存在。
