Fig. 10


Radial profiles at t = 1.5 Tdisk for column density Σ and rotational velocity vrot for all simulations with the highest resolution on the finest grid, normalized in radial direction. The simulation with Qinit = 3 is added for comparison. The density distributions for all radii show similarities. However, the simulation with r = 100 AU and Qinit = 1 shows its single peak at ~52 AU and the negative slope at the outer edge of the disk is much shallower than the slope of the other simulations with Qinit = 1. The velocity distributions for all radii show a similar trend. The simulation with r = 10 AU abruptly goes down in velocity. This behavior might be due to the very sharp transition from disk material (with approximately Keplerian velocity profile) to surrounding material (with approximately zero velocity).
