附近的热发射中子星

Nearby, Thermally Emitting Neutron Stars

D. L. Kaplan

摘要:

我们描述了ROSAT全天巡天中发现的热发射中子星样本。我们讨论了这些天体的基本观测性质,并得出结论,它们是附近的中年恒星,具有中等的磁场,我们通过它们的冷却辐射看到。虽然这些物体在非常高的密度和磁场下作为物质的探针可能非常有用,但我们对它们表面发射的缺乏了解限制了它们目前的用途。我们讨论这个和其他悬而未决的问题:一个源的光谱演化和这个人口的整体脉冲星人口的关系。

英文摘要:

We describe a sample of thermally emitting neutron stars discovered in the ROSAT All-Sky Survey. We discuss the basic observational properties of these objects and conclude that they are nearby, middle-aged pulsars with moderate magnetic fields that we see through their cooling radiation. While these objects are potentially very useful as probes of matter at very high densities and magnetic fields, our lack of understanding of their surface emission limits their current utility. We discuss this and other outstanding problems: the spectral evolution of one sources and the relation of this population to the overall pulsar population.
