通过星光偏振数据揭示PSR B2224+65周围吉他星云中脉冲星X射线丝状物与磁场的对齐关系。

摘要:

PSR B2224+65周围的吉他星云中,脉冲星X射线丝状物可能与局部磁场对齐。我们提供了新的RoboPol恒星偏振数据,沿视线方向分布于脉冲星。中间磁化尘埃的偏振效应使我们能够提取尘埃加权的磁场模型。如果我们假设脉冲星位于其视差估计距离范围的更远区域,则检测到的磁场角度与丝状物一致。

英文摘要:

The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed along the line-of-sight to the pulsar. The polarizing effect of intervening magnetized dust allows us to extract a model for the dust-weighted magnetic field. We detect a magnetic field angle consistent with the filament if the pulsar is located in the more distant zone of its parallax-estimated distance range.
