论文摘要
在这项工作中，通过考虑特定的度量度量$ g_ {rr} $，可以获得各向异性物质分布中爱因斯坦字段方程的精确解决方案。为了检查模型的可行性，我们研究了逼真的恒星的所有物理特征。发现该模型可能是稳定的，并且绝热索引大于$ \ frac {4} {3} $。该模型已被分析为紧凑型星\ TextBf {4U 1538-52}。
In this work, an exact solution of Einstein's field equations in isotropic coordinates for anisotropic matter distribution is obtained by considering a particular metric choice of metric potential $g_{rr}$. To check the feasibility of the model, we have investigated all the physical characteristics of a realistic star. It is found that the model is potentially stable, and the adiabatic index is greater than $\frac{4}{3}$. The model have been analysed for Compact star \textbf{4U 1538-52}.
