Not enough frames to capture evolution (where I suspect the tidal forces may be apparent). Requeued with 1/10th time. However, top view shows clear Coriolis effect. Looks perhaps a bit stronger but otherwise consistent with and given ​Fig. 6.

Unable to start from steady-state run, planet in incorrect position. At frame 760, there still appears to be some subsonic material at the edges, but this may just be because it hasn't yet blown out the entire ambient. The flow profile seems to be more strongly entrained up- and downwind than the above run.

Next?

May be best to run a (slightly larger?) box to steady state with the planet located correctly (using HD209458b orbital parameters - appropriate?), then add stellar gravity and rotation.
