Neutron stars and black holes are the most compact astrophysical objects in the universe. Their strong gravitational fields allow us to explore a regime of physics inaccessible in terrestrial experiments and to test theories of gravitational physics. Although black holes are reasonably simple objects to describe (they are merely empty space), neutron stars are considerably more difficult. This is because they are the densest configurations of matter possible which are stable to gravitational collapse. The density in the central core of a neutron star can be many times more dense than nuclear matter. Since experiments on Earth can't reproduce such high densities, the internal structure of a neutron star is not well understood.

中子星和黑洞是宇宙中最致密的天体。它们强大的引力场使我们能够探索在地球实验中无法实现的物理机制，并测试引力物理学理论。虽然黑洞是相当简单的对象来描述（他们只是空的空间），中子星是相当困难的。这是因为它们是物质可能的致密构型，对于引力坍缩是稳定的。中子星星中央核心的密度可能比核物质的密度大很多倍。由于地球上的实验无法重现如此高的密度，中子星星的内部结构还没有得到很好的理解。
