Surface density map of simulation 0.05-on. The overall density structure is qualitatively similar for all simulations calculated for this work, as sketched in Fig. 3. The black circle denotes the Be star, and the black star, the companion. The white circles and numbers mark the radial distance in R_eq. The three colored bands correspond to the main regions of interest: the wedge that contains the secondary (yellow), the wedge opposite to the secondary (blue), and a wedge that includes the bridge (green).
