论文摘要
由超音速失控的脉冲星产生的脉冲星风云(pwne)可以以尾巴和突出的喷气机的形式呈现延伸的X射线结构。在这封信中,我们报告了$ \ sim $ 130 ks对PWN的分析,周围是PSR $ \,$ j1135-6055 $ \ sim $ \ sim。该系统显示出不确定起源的双极喷气样结构,这是脉冲星周围的紧凑型星云,可能是由弓形冲击形成的,以及脉冲星快速运动产生的尾巴。这些结构的频谱和形态特性在其他失控的脉冲星中显示出与PWNE的强烈相似性,例如PSR J1509-5850和Geminga。我们讨论了它们的物理起源,考虑了典型的PWN和JET形成模型,以及替代场景,这些场景在高能颗粒逃脱到环境磁场之后,还可以产生延长的喷气样特征。
Pulsar wind nebulae (PWNe) produced from supersonic runaway pulsars can render extended X-ray structures in the form of tails and prominent jets. In this Letter we report on the analysis of $\sim$130 ks observations of the PWN around PSR$\,$J1135-6055 obtained with the Chandra satellite. The system displays bipolar jet-like structures of uncertain origin, a compact nebula around the pulsar likely formed by the bow shock ahead of it, and a trailing tail produced by the pulsar fast proper motion. The spectral and morphological properties of these structures reveal strong similarities with the PWNe in other runaway pulsars like PSR J1509-5850 and Geminga. We discuss their physical origin considering both canonical PWN and jet formation models as well as alternative scenarios that can also yield extended jet-like features following the escape of high-energy particles into the ambient magnetic field.
