Three-dimensional contours of the mass density for the LF (semitransparent blue) and HS (red) configurations. The black arrow indicates the approximate direction of the arriving wind, while the vertical direction is aligned with the orbital angular momentum. We note the axisymmetry of the LF flow structure around the mean direction of wind arrival, whereas the HS flow is compressed in the orbital plane and forms a characteristic channel reminiscent of the stream of matter in RLOF systems. Same scale as Fig. 3.
