标题： What we can learn from observations of cooling neutron stars

摘要： 采用一种通用的玩具模型来分析具有核子和奇异芯组成的中子星（NS）的冷却情况。 该模型包含了描述慢速和增强中微子发射强度的参数，以及慢速发射转变为增强发射的密度下限和上限。 讨论了利用目前及未来对孤立中年中子星的观测来限制这些参数的可能性。 显示英文摘要

摘要： A generic toy model of a cooling neutron star (NS) is used to analyze cooling of NSs with nucleon and exotic composition of the cores. The model contains the parameters which specify the levels of slow and enhanced neutrino emission as well as the lower and upper densities of the layer where the slow emission transforms into the enhanced one. The prospects to constrain these parameters from the present and future observations of isolated middle-aged NSs are discussed.
