Two-dimensional snapshots of the CD on the orbital plane at 1 h intervals within a period of 3 h for (a) a top-heavy (k = 2) high-density (f = 0.01), (b) a bottom-heavy (k = 3) high-density (f = 0.01), (c) a top-heavy (k = 2) low-density (f = 0.1), and (d) a bottom-heavy (k = 3) low-density (f = 0.1) clump distribution. The black dashed lines correspond to a smooth stellar wind. The horizontal gray lines mark the CD size used to compute the light curves in Fig. 9.
