摘要:
中子星为探测致密核物质的性质提供了独特环境。本文对两种中子星结构建模方法进行了比较研究:基于手征有效场论的方法和MUSES计算引擎框架,后者对三个密度区域采用三种不同方法。我们分析了得到的质量-半径关系,讨论了两种方法各自的优点和局限性。
英文摘要:
Neutron stars provide a unique environment to probe the properties of dense nuclear matter. In this work, we present a comparative study between two approaches to modeling the neutron star structure: a Chiral Effective Field Theory based approach and the MUSES Calculation Engine framework, which uses three different approaches for the three density regions. We analyze the resulting mass-radius relations, discussing the respective advantages and limitations of the two methods.
