Various theoretical arguments motivate an expectation of a phase transition in matter at extreme densities above nuclear density, accompanied by hopes that gravitational wave observations may reveal the properties of such a transition. Instead of adopting a particular theory, we consider here a generic form of first order phase transition using a piecewise polytropic equation of state, and evolve both isolated neutron stars and neutron star binaries, including unequal mass binaries and, in some cases, magnetic field, looking at dynamical effects. Of particular interest are effects that may be observable either via gravitational waves or electromagnetic observations.

高密度相变对中子星动力学的影响

各种理论争论激发了对物质在高于核密度的极端密度下发生相变的预期，同时希望引力波观测可以揭示这种相变的性质。我们不采用特定的理论，而是在这里考虑使用分段多方状态方程的一阶相变的一般形式，并演化孤立的中子星和中子星双星，包括不等质量的双星，在某些情况下，还有磁场，看动态效果。特别令人感兴趣的是可以通过引力波或电磁观测观察到的效应。
