Density profiles with the contours of the magnetic field vector potential at the final stage of the simulations. The first row presents simulations with no self-gravity and either no magnetic field (left panel), β = 100 (middle panel), or β = 10 (right panel). The second row presents simulations with self-gravity and either no magnetic field (left panel), β = 100 (middle panel), or β = 10 (right panel). The simulations assume a vertical magnetic field configuration. Parameters: A₀ = 0.3, S = 1.0. The models shown are A03-S10-nSG-R12, A03-S10-nSG-wMF, and A03-S10-nSG-sMF (top row), and A03-S10-SG-R12, A03-S10-SG-wMF, and A03-S10-SG-sMF (bottom row), as listed in Table A.1.
