论文摘要
我们报告了PSR J2030+4415的新X射线和光学观察，这是一种带有H $α$弓冲击的伽马射线脉冲星。这些数据揭示了弓休克顶点的速度结构，并在其内部解决了异常的X射线结构。此外，该系统将显示一个非常长的细丝，将至少$ 5^\ prime $以$ \ sim 130^\ circ $扩展到Pulsar Motion Vector。与短期档案曝光相比，仔细的天文统计在85 mas yr $^{ - 1} $中检测到PULSAR的适当运动。使用H $α$速度结构，这使我们可以估计距离为$ 0.75 $ kpc。
We report on new X-ray and optical observations of PSR J2030+4415, a Gamma-ray Pulsar with an H$α$ bow shock. These data reveal the velocity structure of the bow shock apex and resolve unusual X-ray structure in its interior. In addition the system displays a very long, thin filament, extending at least $5^\prime$ at $\sim 130^\circ$ to the pulsar motion vector. Careful astrometry, compared with a short archival exposure, detects the pulsar proper motion at 85 mas yr$^{-1}$. With the H$α$ velocity structure this allows us to estimate the distance as $0.75$ kpc.
