I report the detection of linear X-ray features associated with PSR B2224+65, based on a new Chandra observation, plus two obtained ∼6 and 12 yr earlier. This mid-aged pulsar is known for its extreme proper motion and its associated guitar-shaped optical nebula in the opposite direction. The main jet-like feature with the same proper motion is long and directed 62 away from the nebula, which is associated with a faint X-ray tail detected for the first time. Also now clearly revealed are the sharp forward edge and epoch-dependent substructures of the feature and its curvature near the pulsar, as well as a much fainter/shorter counter-jet. Magnetic field appears to play a central role in the formation of the features, which represent the synchrotron radiation of energetic particles leaked out from the bow shock nebula through small holes, produced probably by localized magnetic reconnection, and streaming along interstellar magnetic field lines.

我报告了基于新的Chandra观测值，检测到与PSR B2224 + 65相关的线性X射线特征，以及在6年和12年之前获得的两个。这个中年脉冲星以其极佳的运动和相反方向的关联的吉他状星云而闻名。具有相同固有运动的主要喷射状特征是并指向62远离星云，这与首次检测到的微弱X射线尾巴有关。现在还清楚地显示出该特征的锋利的前边缘和与历时有关的子结构及其在脉冲星附近的曲率，以及更暗淡/较短的反向射流。磁场似乎在这些特征的形成中起着核心作用，这些特征代表着高能粒子的同步加速器辐射通过小孔从弓形激波星云中泄漏出来，这可能是由于局部磁场重新连接而产生的，并沿着星际磁场线流动。
