Specific angular momentum ∫_r<Rr × ρv dV as a functionof the sphere radius R for runs SUPA (left), SUPAS (middle), and SUBA (right). Components of the specific angular momentum vector are displayed at t = 0 kyr (dotted lines), t = 30 kyr (dashed lines), and t = 50 kyr (full lines). Time t = 0 kyr describes the initial conditions, t = 30 kyr is roughly the first sink formation epoch (a rotating structure is already present), and t = 50 kyr corresponds to a massive protostar surrounded by its accretion disk. Components along x, y, and z are shown in blue, orange, and green, respectively.
