Density maps in the plane of the disc and perpendicular to it for the models HYDRO (top), MU5I (second line), MU2AD (third line), MU5AD (fourth line), and MU5ADf (bottom). Two different times are represented: M_⋆ = 5 M_⊙ (left) and M_⋆ = 10 M_⊙ (right). The mass M_⋆ gives the total mass converted into sink particles at each snapshot. The arrows represent the velocity vectors in the plane.
