论文摘要
我们基于广义的Skyrme模型提出了一个新的核问题状态方程，该方程与所有当前对中子恒星的特性的约束是一致的。该广义模型仅取决于与不同子模型占主导地位的压力值范围相关的两个自由参数，并且可以调整它们，以便可以满足天体物理和重力波测量的质量 - 拉迪乌斯和可变形性约束。我们的结果支持Skyrme模型及其概括作为低能能源有效的核物质现场理论描述的良好候选，即使在极端条件下，例如中子恒星内部。
We propose a new equation of state for nuclear matter based on a generalized Skyrme model which is consistent with all current constraints on the observed properties of neutron stars. This generalized model depends only on two free parameters related to the ranges of pressure values at which different submodels are dominant, and which can be adjusted so that mass-radius and deformability constraints from astrophysical and gravitational wave measurements can be met. Our results support the Skyrme model and its generalizations as good candidates for a low energy effective field-theoretic description of nuclear matter even at extreme conditions such as those inside neutron stars.
