摘要

Alfven waves can dissipate their energy by means of nonlinear mechanisms, and constitute good candidates to heat and maintain the solar corona to the observed few million degrees. Another appealing candidate is nanoflare reconnection heating, in which energy is released through many small magnetic reconnection events. Distinguishing the observational features of each mechanism is an extremely difficult task. By setting up a. 1.5D MHD model of a loop we test both heating mechanisms and derive observational quantities. The obtained coronae differ in many aspects; for instance, in the flow patterns along the loop, flow velocities, and the simulated intensity profile that Hinode/XRT would observe. The heating events in the loop exhibit power-law distributions in frequency, whose indexes differ considerably depending on the heating mech-anism and its location along the loop. We thus test the observational signatures of the power-law index as a diagnostic tool for the above coronal heating mech-anisms.
