Top: sketch of disk wind models with different mass loading. The length of the streamlines is proportional to the local mass-loss rate. Top left: the bulk of the disk wind is ejected along streamlines near the star (γ = 4, model B1). Top right: the bulk of the disk wind is ejected along the outer streamlines (γ = 1, model B2). Middle: kinematics for models B1 (left) and B2 (right). The poloidal velocity at the first streamline (solid) and the sixth outermost streamline (dashed) are presented. The dotted lines represent the rotational velocity component. Bottom: the computed Hα (blue), Paα (green), and Brγ (red) line profiles (normalized to one) of models B1 (left) and B2 (right) for a disk inclination angle (the angle between the system axis and the viewing direction) of 20°.
