中子星内部结构

The inner structure of neutron stars

  • 摘要: 中子星是宇宙中一类极端致密的天体,其平均密度超过饱和核物质密度。对这类天体的研究,可以帮助人们了解极端条件下的物理性质,特别是深化关于引力和强力的认识。文章介绍了脉冲星和中子星的概念,并重点阐述了中子星内部结构的不同模型,以及如何通过最大质量和潮汐形变量等观测来检验这些模型。未来发现更多的双中子星并合或中子星黑洞并合事件,有望最终揭开中子星内部结构之谜。

     

    Abstract: Neutron stars are extremely compact objects with an average density higher than that of the saturate nuclear matter. Exploring the nature of such objects can help us to understand physics under extreme conditions, especially the gravitational and strong forces. This paper introduces the concepts of pulsars and neutron stars, as well as various models of the interior structure of the latter. More importantly, we shall show how to test such models observationally by determining various properties related to the equation of state, such us the maximum mass and tidal deformability. Detecting further merger events of binary neutron stars and/or neutron star-black hole binaries will certainly help to unveil the inner structure of neutron stars.
