Effect of the background heating on TNE cycles. LareJ results for time dependent footpoint heating. The 2D plots show the time evolution of the temperature as a function of position along the loop. The various panels represent different values of background heating (Q_bg). On the right of the 2D plots, we display the evolution of the coronal averaged temperature (computed by spatially averaging over the uppermost 25% of the loop). At the bottom of the 2D plots, we show the time averaged footpoint heating profile (blue line, left-hand axis) imposed on top of the temperature initial condition (red line, right-hand axis).
