And here is schematic showing the star/planet surfaces, their sonic surfaces, and the location of the bow shock, hill radius, and coriolis radius. Note the bow shock will likely be closer to the planet due to the planet wind being sub-parker and that the coriolis radius will probably be larger for the same reason.

And here is the same setup, but with a stellar density 10x higher
