论文摘要
从不对称二进制的引力波观察到重型中子星的可能性,但这些挑战对状态的中子恒星方程式构成了挑战。我们通过在QCD物质来源的声速中引入非平凡结构来构建重型中子星,这无法通过频谱表示可以很好地恢复。他们的惯性矩,爱情数量和四极力矩很小,因此可能需要提高灵敏度,以通过引力波来测试这种可能性,这对于第三代探测器来说是可行的。
The observation of gravitational waves from an asymmetric binary opens the possibility for heavy neutron stars, but these pose challenges to models of the neutron star equation of state. We construct heavy neutron stars by introducing non-trivial structure in the speed of sound sourced by deconfined QCD matter, which cannot be well recovered by spectral representations. Their moment of inertia, Love number and quadrupole moment are very small, so a tenfold increase in sensitivity may be needed to test this possibility with gravitational waves, which is feasible with third generation detectors.
