论文摘要
在本文中，我们提出了一种物理条件，通过在最小几何变形方法的框架中通过重力解耦来将内部各向同性溶液扩展到各向异性域。特别是，通过使用让人联想到经典各向异性因子的表达式，我们可以关闭方程式的解耦系统，并可以找到新的各向异性解决方案。例如，我们扩展了井 - 已知的Tolman IV。
In this article, we propose a physical condition to extend interior isotropic solutions to anisotropic domains by gravitational decoupling in the framework of the Minimal Geometric Deformation approach. In particular, it is found that by using an expression reminiscent of the classical anisotropy factor, we can close the decoupling system of equations and a new anisotropic solution can be found. As an example, we extend the well--known Tolman IV.
