论文摘要
接近饱和密度的核对称能的行为对于我们对密集核物质的理解很重要。该密度依赖性可以通过核对称能及其在核饱和密度下评估的衍生物进行参数。在这项工作中，我们表明，中子恒星的核心壳接口模式对这些参数敏感，通过（密度加权的）剪切速度内的（密度加权）剪切速度，这又取决于密集物质的对称能曲线。我们计算中子星四极杆（$ \ ell = 2 $）的频率必须由其二进制合作伙伴的潮汐场驱动以触发谐振的破碎耀斑（RSF）。我们证明，来自中子星合并的RSF和重力波chirp的巧合多通电器时间将使我们能够对与当前核实验的对称能量参数放置在对称能量参数上。
The behaviour of the nuclear symmetry energy near saturation density is important for our understanding of dense nuclear matter. This density dependence can be parameterised by the nuclear symmetry energy and its derivatives evaluated at nuclear saturation density. In this work we show that the core-crust interface mode of a neutron star is sensitive to these parameters, through the (density-weighted) shear-speed within the crust, which is in turn dependent on the symmetry energy profile of dense matter. We calculate the frequency at which the neutron star quadrupole ($\ell = 2$) crust-core interface mode must be driven by the tidal field of its binary partner to trigger a Resonant Shattering Flare (RSF). We demonstrate that coincident multimessenger timing of an RSF and gravitational wave chirp from a neutron star merger would enable us to place constraints on the symmetry energy parameters that are competitive with those from current nuclear experiments.
