论文摘要
我们研究大型磁场对旋转黑洞附近带电颗粒动力学的影响。我们考虑了一种场景,在赤道平面中最初的中性颗粒在电离中被电离,因此它们因充电过程而破坏了稳定。然后将带电颗粒的比例从赤道平面加速,然后像具有相对论速度的轨迹一样跟随射流。我们探索非轴对称系统,其中磁场相对于黑洞旋转。我们以数字研究系统,以定位逃避轨迹的区域并计算末端逃逸速度。通过打破轴向对称性,我们注意到未结合轨道的分数增加,从而使超偏移速度加速。
We study the effects of large scale magnetic fields on the dynamics of charged particles near a rotating black hole. We consider a scenario in which the initially neutral particles on geodesic orbits in the equatorial plane become ionized, and hence they are destabilized by the charging process. Fraction of charged particles are then accelerated out of the equatorial plane and then follow jet like trajectories with relativistic velocities. We explore non axisymmetric systems in which the magnetic field is inclined with respect to the black hole spin. We study the system numerically in order to locate the zones of escaping trajectories and compute the terminal escape velocity. By breaking the axial symmetry we notice increasing fraction of unbound orbits which allow for acceleration to ultrarelativistic velocities.
