论文摘要
最近，一种一般的形式主义在这里研究了牛顿多型的各向异性流体，这扩展到了相对论方案。因此，假定径向和切向压力的流体压力都可以满足状态的多粒子方程。这样做，可以获得并解决广义的车道 - 填充方程。获得了一些特定的模型，并讨论了它们的物理特性。
A general formalism recently proposed to study Newtonian polytropes for anisotropic fluids is here extended to the relativistic regime. Thus, it is assumed that a polytropic equation of state is satisfied by, both, the radial and the tangential pressures of the fluid. Doing so the generalized Lane--Emden equations are obtained and solved. Some specific models are obtained, and their physical properties are discussed.
