On average, MADs have a well-defined hourglass-shaped structure, consisting of an inflowing disk region and outflowing wind and jet regions. We depict the time-averaged axisymmetrized flow of angular momentum within the disk, wind, and jet regions at time t = 80,000–120,000 r g /c out to 100 r g in the right column and out to 25 r g in the left column. In the top row, we plot contours of the gas density, and in the bottom row, we plot contours of the plasma β. We have labeled each region: The solid green lines are the disk-wind boundaries, and the solid black and white lines are the wind-jet boundaries. The dashed green line shows the typical thermal definition of the disk thickness (Equation (9)). The black streamlines sketch the flow of angular momentum (Equation (1)).
