论文摘要
生成一个满足多通用剂约束的状态方程的集合，我们统计确定了中子星（NSS）中发现的密集物质的特性。我们计算出声音和痕量异常的速度，并证明它们是在最大巨大NS中心朝着共形值驱动的。声音速度的局部峰被证明位于QCD物质中与解密和渗透条件一致的能量和粒子密度的值。我们还分析了在可能的临界行为残留物的背景下，净 - 巴里昂数量密度的波动。我们发现，这些波动的差异的全球最大值以超出NSS内部的密度而出现。
Generating an ensemble of equations of state that fulfill multimessenger constraints, we statistically determine the properties of dense matter found inside neutron stars (NSs). We calculate the speed of sound and trace anomaly and demonstrate that they are driven towards their conformal values at the center of maximally massive NSs. The local peak of the speed of sound is shown to be located at values of the energy and particle densities which are consistent with deconfinement and percolation conditions in QCD matter. We also analyze fluctuations of the net-baryon number density in the context of possible remnants of critical behavior. We find that the global maxima of the variance of these fluctuations emerge at densities beyond those found in the interiors of NSs.
