论文摘要
在这项工作中，我们使用XMM-Newton的数据研究了由成熟的Pulsar PSR B1929+10提供动力的X射线弓形星云，并有效暴露于$ \ sim $ 300 ks，迄今为止对该系统进行了最深入的研究。我们发现，X射线轴向流出的长度长达$ \ sim $ 8弧度分钟比正确的运动方向分钟，这比上一项研究中报道的结果长两个。此外，我们发现了两个微弱的侧向流出相对于正确运动的横向延伸的证据。我们还发现了沿轴向流出的光谱硬化的指示，这表明可能会沿此功能发生某些加速过程。
In this work, we study the X-ray bow-shock nebula powered by the mature pulsar PSR B1929+10 using data from XMM-Newton, with an effective exposure of $\sim$ 300 ks, offering the deepest investigation of this system thus far. We found the X-ray axial outflow extends as long as $\sim$ 8 arc minute behind the proper motion direction, which is a factor of two longer than the result reported in the previous study. Furthermore, we found evidence of two faint lateral outflows extending laterally with respect to the proper motion. We also found indications of spectral hardening along the axial outflow, suggesting that certain acceleration processes might occur along this feature.
