我们模拟了超流中子星的冷却，其中的核子核是禁止直接URCA过程的。我们采用密度相关的临界温度，以及恒星核中单态质子和三态中子配对的临界温度，并考虑了强质子配对(最大K)和中等中子配对(K)。当恒星内部温度低于T时，由于中子库珀配对而产生的中微子光度LCP表现为T8，就像修正的URCA过程(在非超流恒星中)所产生的那样，但要高出大约两个数量级。在这种情况下，库珀配对中微子发射的作用就像是一种增强型冷却剂。通过调整密度依赖关系，我们可以解释在没有直接Urca过程或Kaon/pion凝聚物质或夸克物质中类似过程的情况下冷却孤立中子星的观测结果。
We simulate cooling of superfluid neutron stars with nucleon cores where the direct Urca process is forbidden. We adopt density-dependent critical temperatures and of singlet-state proton and triplet-state neutron pairing in a stellar core and consider strong proton pairing (with maximum K) and moderate neutron pairing ( K). When the internal stellar temperatureTfalls below , the neutrino luminosityLCPdue to Cooper pairing of neutrons behavesT8, just as that produced by the modified Urca process (in a non-superfluid star) but is higher by about two orders of magnitude. In this case the Cooper-pairing neutrino emission acts like an enhanced cooling agent. By tuning the density dependence we can explain observations of cooling isolated neutron stars in the scenario in which the direct Urca process or a similar process in kaon/pion condensed or quark matter are absent.
