标题： The XMM-Newton view of the radio-quiet neutron star 1E 1207.4-5209

摘要： 我们利用 XMM-Newton 卫星上的高吞吐量 EPIC 相机观测了宁静无线电脉冲星 1E 1207.4-5209。 该源的能谱由两个具有显著亚结构的宽吸收特征组成，并显示出明显的相位依赖性。 我们认为这些特征强烈表明存在包含重元素的磁化大气层。 显示英文摘要

摘要： We have observed the radio-quiet X-ray pulsar 1E 1207.4-5209 with the high throughput EPIC cameras onboard XMM-Newton. The spectrum of this peculiar source is characterized by two broad absorption features which present significant substructures and show a clear phase-dependence. We believe that these features represent a strong evidence for the presence of a magnetized atmosphere containing heavy elements.
