Gas flows around the planet for the run ℳ₃₀₀ at t = 490.75 orbits. The background color represents the logarithm of the gas surface density. The black streamlines and the LIC (Line Integral Convolution) correspond to the radial and azimuthal components of the horizontal velocity, in the midplane and in the planet’s reference frame. The white lines indicate the estimated inner and outer gap edge. The right panel focuses on the horseshoe region.
