论文摘要
本文致力于通过扩展的几何变形去耦技术评估精确的各向异性球形溶液，以用于静态自我填充系统。为此，我们考虑了各向同性的Tolman IV溶液，并通过转换时间和径向度量电位来扩展到各向异性结构域。为了检查内部各向异性解决方案的身体生存能力和稳定性，我们绘制了恒星的X-I和PSR J 1416-2230的恒星的能量边界，TOV方程，因果关系和绝热指数。发现两个获得的模型都表现出逼真的行为，因为它们满足了所有物理约束以及稳定标准。我们得出的结论是，扩展的重力去耦方法提供了更熟练的结果，以讨论恒星结构的内部配置。
This paper is devoted to evaluating exact anisotropic spherical solutions for static self-gravitating systems through extended geometric deformation decoupling technique. For this purpose, we consider an isotropic Tolman IV solution and extend it to anisotropic domain by transforming both temporal as well as radial metric potentials. To examine the physical viability and stability of interior anisotropic solutions, we plot energy bounds, TOV equation, causality condition and adiabatic index for the stars Her X-I and PSR J 1416-2230. It is found that both obtained models show realistic behavior as they fulfill all physical constraints as well as stability criterion. We conclude that the extended gravitational decoupling approach provides more proficient results to discuss the interior configuration of stellar structures.
