论文摘要
可以根据中子恒星冷却理论来解释中子星的年龄和热仪，从观察结果中推断出来，以获取有关中子星室内超浓度物质特性的信息。我们介绍了具有相对较弱或中等强的磁场的中年中子星的估计年龄，表面温度和热光度的调查，这对于这些目的可能很有用。该目录包括从文献中选择的结果，并补充了一些冷却中子星的光谱分析的新结果。将数据与理论进行比较。我们表明，对于恒星核心中的中子超流体较弱的模型，理论冷却曲线与观测值的总体一致性大大改善。
Ages and thermal luminosities of neutron stars, inferred from observations, can be interpreted with the aid of the neutron star cooling theory to gain information on the properties of superdense matter in neutron-star interiors. We present a survey of estimated ages, surface temperatures and thermal luminosities of middle-aged neutron stars with relatively weak or moderately strong magnetic fields, which can be useful for these purposes. The catalogue includes results selected from the literature, supplemented with new results of spectral analysis of a few cooling neutron stars. The data are compared with the theory. We show that overall agreement of theoretical cooling curves with observations improves substantially for models where neutron superfluidity in stellar core is weak.
