| Zusammenfassung |
| We present the first results of simulations of giant polar plumes
generated by Alfvénic motions of their magnetic footpoints. We use a
2.5D axisymmetric MHD numerical model of an isothermal corona and slow
solar wind with transparent boundary conditions. Alfvén waves are
continuously injected from the coronal base and a dense jet (plume)
forms just above a small magnetic bipole embedded in an unipolar flux
region. The jet presents a series of blobs which propagate outwards
along its axis as slow mode wavefronts. |
