摘要：

中子星的合并创造了超核密度$n\gtrsim n_{\rm nuc}\simeq 0.17 {\rm fm}^{-3}$和中等温度$50\lesssim T \lesssim 90 {\rm MeV}$的条件。因此，这些事件探测QCD物质的密度-温度相图的敏感区域。我们研究光子生产的QCD共形异常的信号可能过渡到夸克自由度在合并。我们讨论的能量损失由于光子辐射作为一种冷却机制，是敏感的夸克物质的体积粘度和热导率。

英文摘要：

Mergers of binary neutron stars create conditions of supranuclear density $n\gtrsim n_{\rm nuc}\simeq 0.17 {\rm fm}^{-3}$ and moderate temperature $50\lesssim T \lesssim 90 {\rm MeV}$. These events thus probe a sensitive region of the density-temperature phase diagram of QCD matter. We study photon production by the QCD conformal anomaly for a signal of a possible transition to quark degrees of freedom during the merger. We discuss energy loss due to photon radiation as a cooling mechanism that is sensitive to the bulk viscosity and thermal conductivity of the quark matter.
