Local rotational velocity (v) divided by the local Keplerian velocity (v_K) with respect to mass coordinate (M). Depicted are model sequences lm10810-3 and lm10806-3. Solid lines represent the f_acc = 1.0 case (lm10810-3), dotted lines the f_acc = 0.6 case (lm10806-3). The color bar indicates the time-coordinate of the profile. The black lines indicate the mass coordinate of the point of ignition for the respective model. The solid black line is valid for f_acc = 1.0 and the dotted line for f_acc = 0.6.
