论文摘要
使用完整的3尺寸一般宽容性流体动力学模拟，对相等和不平等的中子星星二进制二进制物具有与从GW170817的Inspiral推论的属性一致的，我们对合并后可能发生的夸克形成过程进行了详细的研究。我们使用三个状态方程与基于V-QCD的新颖有限温度框架得出的当前PULSAR观测值是一致的，该框架是V-QCD，这是一种用于量子染色体动力学的非扰动仪/重力模型。通过这种方式，我们确定了三个不同的合并后阶段，在这些阶段中混合了混合的Baryonic和Quark Matter以及纯夸克物质。合并后的相位过渡触发的崩溃已经$ \ sillsim 10 \，\ rm {MS} $表明，我们的状态方程式的最柔软版本实际上与预期的GW170817的预期第二长的合并后寿命。我们的结果强调了对二进制中子星级合并的多理智观察在约束核物质状态方程，尤其是在其最极端政权中的影响。
Using full 3+1 dimensional general-relativistic hydrodynamic simulations of equal- and unequal-mass neutron-star binaries with properties that are consistent with those inferred from the inspiral of GW170817, we perform a detailed study of the quark-formation processes that could take place after merger. We use three equations of state consistent with current pulsar observations derived from a novel finite-temperature framework based on V-QCD, a non-perturbative gauge/gravity model for Quantum Chromodynamics. In this way, we identify three different post-merger stages at which mixed baryonic and quark matter, as well as pure quark matter, are generated. A phase transition triggered collapse already $\lesssim 10\,\rm{ms}$ after the merger reveals that the softest version of our equations of state is actually inconsistent with the expected second-long post-merger lifetime of GW170817. Our results underline the impact that multi-messenger observations of binary neutron-star mergers can have in constraining the equation of state of nuclear matter, especially in its most extreme regimes.
