Temporal evolution of the DEM for cases S, V and Y (left, middle and right columns, respectively). Time runs from the top to the bottom rows (as indicated in the inset legend on each individual panel, where time is indicated in units of t0). For each one of the cases represented, the first row corresponds to the linear phase of the kink-instability, the second row represents the period of maximum thermal emission, and the third row the beginning of the relaxation phase. The upper tail which forms in the DEM distribution corresponds to the plasma heated after the development of the kink-instability in the magnetic flux rope. This corresponds to a hot plasma component, which is particularly distinguishable in case V. The maximum temperature reached depends mostly on flux rope’s magnetic field amplitude, approximately as ~ B2 (cf. Pinto et al. 2015).
