| Abstract: |
In spite of the large number of magnetohydrodynamic (MHD) simulations of emerging flux tubes in the solar atmosphere, radiation properties of the phenomenon remain poorly understood. This is because heating at the footpoints of the emerging magnetic field lines is significant and the effects associated with heat conduction and evaporation have largely been neglected. In this study, we have performed three-dimensional (3-D) multi-wavelength radiation transfer calculations on a MHD model of an emerging flux tube in order to examine the MHD model and also to identify a possible heating mechanism for explaining the properties of observed X-ray coronal loops. It is found that the current dissipation model is difficult for reproducing the structure of X-ray loops observed by Hinode XRT and Yohkoh SXT. This suggests that alternative models of the heating process should be incorporated into our MHD models. We left unresolved issues of the heating process as future work. |
