Mass of the envelope shell as a function of the free-fall time. The green solid line is the total mass in the shell, while the red lines corresponds to the mass contained in the rotationally supported torus. Here, the solid, long dashed and short dashed lines show the models with the specific angular momentum normalized with x = 1.5, 3, and 7, respectively. All models assume that 28% of the stellar envelope is accreted onto the BH, and the rest of the mass is evacuated as a massive wind.
