论文摘要
在脉冲星磁层中研究了加速电子的轨迹和辐射，该磁层近似为Deutsch溶液的电磁场。由于电子在中子恒星表面附近迅速加速至超相关速度，因此电子速度矢量（然后是其轨迹）源自洛伦兹力量和辐射反作用力之间的平衡，这使电子轨迹轨迹和磁场线之间的螺距角度在磁圈的大多数中是非零的。在这种情况下，计算了具有单能形式的加速电子的同步辐射的光谱能分布（SED）。我们的结果表明：（i）音高角度是在空地线区域中电子位置（$ r，θ，ϕ $）的功能，并且随着$ r $和$θ$的增加而增加，并增加了倾斜度角度； （ii）曲率半径沿着粒子轨迹变大，（iii）SED取决于发射位置，在该位置上，同步子辐射在X射线频带中起着重要作用，在X射线频带和曲率辐射中起着重要作用，主要在GEV中起作用，仅在GEV带中起作用，仅由参数$α$α$α$α$α$α$α$α$α$ quam $α$α$α$ quam $α$α$确定
Trajectories and radiation of the accelerating electrons are studied in the pulsar magnetosphere approximated as the electromagnetic field of the Deutsch's solutions. Because the electrons are accelerated rapidly to ultra-relativistic velocity near the neutron star surface, the electron velocity vector (and then its trajectory) is derived from the balance between Lorentz force and radiation reaction force, which makes the pitch angle between electron trajectories and magnetic field lines nonzero in most part of the magnetosphere. In such a case, the spectral energy distributions (SEDs) of synchro-curvature radiation for the accelerating electrons with a mono-energetic form are calculated. Our results indicate that: (i) the pitch angle is the function of electron position ($r, θ, ϕ$) in the open field line regions, and increases with increasing $r$ and $θ$ as well as increasing the inclination angle; (ii) the radius of curvature becomes large along the particle trajectory, and (iii) the SED appears a double peak structure depending on the emission position, where the synchrotron radiation plays an important role in X-ray band and curvature radiation mainly works in GeV band, which is only determined by parameters $α$ and $ζ$
