Top panels: volume gas density in vertical slices, in units of M_A/au³ and logarithmic scale, obtained from a 3D model that includes a giant planet. Each slice passes through the planet location. The distributions are displayed at a binary phase around apocenter passage (left), pericenter passage (center), and shortly thereafter (right). Bottom panels: surface density of the gas, in units of M_A/au² and logarithmic scale, plotted at the same orbital phases as in the top panels.
