Post 2.5D MHD relaxation profiles for the temperature, density, B_z magnetic field, and kink speed of our stratified flux tube. Left: 2D temperature profile for a section of our model up to r = 3 Mm. Top right: 1D profiles along the z direction of the density (black lines) and B_z magnetic field (red lines) at r = 0 (solid lines) and at r = 8 Mm (dashed lines). Bottom right: Profile of the kink speed along the z-axis, with the coronal part (z ∈ [7, 193] Mm) highlighted (dashed orange line).
