Abstract

In the present work we investigate new class of charged isotropic solutions with a linear barotropic equation of state (EoS) in the framework of Einstein–Gauss–Bonnet (EGB) gravity for 5 and 6 dimensional spherically symmetric static distributions. Imposing such a restriction of the EoS, one more further assumption on the metric potentials must be chosen in order to close the system. For example, the constant gravitational potential which is responsible for an isothermal distribution in Einstein gravity and as well as different forms of temporal potential are analyzed. Through graphical analysis we demonstrate that the obtained exact models satisfy the basic elementary astrophysical requirement for physical plausibility.

爱因斯坦-高斯-邦尼重力中线性正压状态方程的带电各向同性解

在本工作中，我们研究了一类新的带线性正压状态方程（EoS）在爱因斯坦-高斯-博内（EGB）重力框架下的5维和6维球对称静态分布的带电各向同性解。施加这样的极限，为了关闭系统，必须选择一个关于度量势的进一步假设。例如，分析了爱因斯坦引力中引起等温分布的恒定引力势，以及不同形式的时间势。通过图形分析，我们证明了所得到的精确模型满足了天体物理学对物理合理性的基本基本要求。
