中子星是宇宙中密度最大、可直接观测的恒星物体，是研究极端物理条件下物质行为的独特天体物理实验室。本书的这一章致力于描述电磁观测，特别是在x射线、光学和无线电波长，可以用来测量中子星的质量和半径，以及这如何导致对超致密物质状态方程的限制。在这项工作中，拥有精确的理论模型来描述天体物理数据至关重要。我们将回顾约束中子星质量和半径的不同方法，讨论过去十年来取得的主要观测结果和理论发展，并展望新的和即将到来的地基和天基天文台如何取得进一步进展。
Neutron stars are the densest, directly observable stellar objects in the universe and serve as unique astrophysical laboratories to study the behavior of matter under extreme physical conditions. This book chapter is devoted to describing how electromagnetic observations, particularly at X-ray, optical and radio wavelengths, can be used to measure the mass and radius of neutron stars and how this leads to constraints on the equation of state of ultra-dense matter. Having accurate theoretical models to describe the astrophysical data is essential in this effort. We will review different methods to constrain neutron star masses and radii, discuss the main observational results and theoretical developments achieved over the past decade, and provide an outlook of how further progress can be made with new and upcoming ground-based and space-based observatories.
