Permanent asymmetry and variations in the distorted CO ro-vibrational line profiles in a disk with an 8   M_J planet orbiting an 1   M_⊙ star at 1 AU (model #8). The subsequent epochs go across and down. The position angle (PA) of the giant planet is shown in each frame. The arrows point to the variable component moving in between  ~± 25   kms^-1. The normalized line flux is shown with the same scale as in Fig. 8a. The snapshots were calculated during one planetary orbit, thus about 2.5 weeks elapsed between the frames. The disk inclinations were 20°, 40° and 60°, shown in blue, green and red colors. For comparison, we displayed the symmetric double-peaked line profiles (dashed lines) emerging from a planet-free disk as well. As can be seen, the line profiles have permanent asymmetry and show a significant change in their shapes within weeks.
