以电荷为振子的内部静态恒星模型

Interior Static Stellar Model with Electric Charge as an Oscillator

A. M. Baranov

摘要:

本文在广义相对论的框架内研究了一种描述充满带电帕斯卡理想流体的静态恒星的模型方法。度规是用邦迪辐射坐标表示的。引力方程通过一个新的变量作为径向坐标的函数进行简化,得到一个非线性振子方程。结果表明,在这种情况下,对于具体的荷电流体能量密度分布规律,Einstein-麦克斯韦方程组的精确解可作为谐振子方程的解而得到。

英文摘要:

A model approach to the description of static stars filled with a charged Pascal perfect fluid within the framework of general relativity is investigated. The metric is written in Bondi's radiation coordinates. The gravitational equations are reduced to a nonlinear oscillator equation after transfomation to a new variable as a function of the radial coordinate. It is shown that in this case exact solutions of the Einstein-Maxwell equations for a concrete energy density distribution law of the charged fluid may be obtained as solution of the harmonic oscillator equation.
