Visualization of disk formation: deviation from gravito-centrifugal equilibrium of the midplane gas as function of radius for four different snapshots in time. Dotted, dashed, dot-dashed, and solid lines corresponds to t = 5, 15, 40, and 80 kyr of evolution, respectively. The bottom panel refers to the simulation including all feedback components, radiation forces are neglected in the simulation data of the upper panel. Outflows and photoionization is accounted for in both simulations shown, both panels present the data from the large-scale mass reservoir simulations.
