一个真实的脉冲星磁层
Toward a Realistic Pulsar Magnetosphere
摘要：
本文给出了脉冲星磁层不服从理想条件${\bf E \cdot B =0}$的磁场和电场结构以及电流和电荷密度。由于粒子的加速和辐射的产生需要平行于磁场的电场分量${\bf E}_\parallel$的存在，非理想脉冲星磁层的结构与脉冲星辐射的产生密切相关。因此，了解非理想脉冲星磁层的结构是很重要的，因为它们与观测结果的比较（包括辐射产生的模型）将描述脉冲星辐射问题的物理和参数。我们实现了各种处方，支持非零值的${\bf E}_\parallel$，并探讨其对所产生的磁层结构的影响。我们生产的解决方案系列涵盖了真空和（理想）无力电动解决方案之间的整个范围。我们还计算了耗散量作为旋转轴和磁轴之间不同角度的磁共振的坡印廷通量的一部分，并得出结论，这是最多20-40%（取决于非理想处方）在对齐的旋转器和10%在垂直的。我们还提出了具有$J=ρc$性质的极限解，并讨论了它们对确定间歇振荡器的“开/关”状态的可能意义。最后，我们发现，解决方案的$J$值大于那些需要空${\bf E}_\parallel$本地产生振荡，潜在的观察数据。
英文摘要：
We present the magnetic and electric field structures as well as the currents and charge densities of pulsar magnetospheres which do not obey the ideal condition, ${\bf E \cdot B =0}$. Since the acceleration of particles and the production of radiation requires the presence of an electric field component parallel to the magnetic field, ${\bf E}_\parallel$, the structure of non-Ideal pulsar magnetospheres is intimately related to the production of pulsar radiation. Therefore, knowledge of the structure of non-Ideal pulsar magnetospheres is important because their comparison (including models for the production of radiation) with observations will delineate the physics and the parameters underlying the pulsar radiation problem. We implement a variety of prescriptions that support nonzero values for ${\bf E}_\parallel$ and explore their effects on the structure of the resulting magnetospheres. We produce families of solutions that span the entire range between the vacuum and the (ideal) Force-Free Electrodynamic solutions. We also compute the amount of dissipation as a fraction of the Poynting flux for pulsars of different angles between the rotation and magnetic axes and conclude that this is at most 20-40% (depending on the non-ideal prescription) in the aligned rotator and 10% in the perpendicular one. We present also the limiting solutions with the property $J=ρc$ and discuss their possible implication on the determination of the "on/off" states of the intermittent pulsars. Finally, we find that solutions with values of $J$ greater than those needed to null ${\bf E}_\parallel$ locally produce oscillations, potentially observable in the data.
