英文摘要 | Previous studies have concluded that the Hall magnetic field structures generated during magnetic reconnection are carried away by kinetic Alfvén waves (KAW). Here we apply a kinetic simulation with an ion/electron mass ratio closer to its natural value and find that open boundary conditions and much-reduced damping rates permit the shear Alfvén waves (SAW) to become the main carrier of wave energy. For magnetotail reconnection these SAW provides efficient transport of wave energy, enhancing the energy input for the Aurora Borealis by orders of magnitude above previous estimates. |
