Pole-on views of the density evolution for the Bs5-Bp1 case. The different panels show the density of the planetary wind in a log color scale (right color bar) at different times as indicated in the top-left corner of each image. The yellow sphere at the center represents the central star. The planet is located to the left of the star and it embedded in the planetary wind. The blue-to-white lines represent the magnetic field lines (left color bar). A movie is available online.
