论文摘要
在这项工作中，我们通过最小的几何变形方法研究了重力去耦框架内质量的额外包装。结果表明，在涉及的一组合适的自由参数之后，通过最小的几何变形扩展了类似的 - 托尔曼iv溶液，不仅获得了额外的质量包装，而且根据绝热索引标准对应于稳定的配置。此外，还表明，额外的填料条件在种子各向同性溶液的紧凑性参数上引起了下限，并严格限制了脱钩参数。
In this work we investigate the extra packing of mass within the framework of gravitational decoupling by means of Minimal Geometric Deformation approach. It is shown that, after a suitable set of the free parameters involved, the like--Tolman IV solution extended by Minimal Geometric Deformation not only acquire extra packing of mass but it corresponds to a stable configuration according to the adiabatic index criteria. Additionally, it is shown that the extra packing condition induce a lower bound on the compactness parameter of the seed isotropic solution and a stringent restriction on the decoupling parameter.
