Specific angular momentum at the equator taken at several time steps corresponding to the inhomogeneous structure in the self-gravitating case (right panels in both rows). The cases without self-gravity are also presented in the left two panels. Two cases of S = 1.4 and S = 2 with A₀ = 0.5 are shown in the top and bottom panels, respectively. During the emergence of inhomogeneities, self-gravity seems to transfer the angular momentum into the black hole. Models are labelled in all panels with symbols referring to Table A.1.
