Density distributions at the centre of the cloud of ideal MHD model (left) and resistive MHD model (right) when ρ_c ∼ 5 × 10⁻³ g cm⁻³. y = 0 planes are shown. The right-hand panel shows the result with STS. The parameters for STS are ν_sts = 0.01, N_sts = 5. The velocity field is shown with red arrows. The thin black lines show the density contour and the thick black line in left-hand panel shows the contour of |v_z| = 0.
