Density perturbation in a cut through ϕ_ρ = π/4 as a function of cylindrical radius, R, and vertical position, ɀ, for 3T simulations of Saturn-mass planets without (above) and with (below) accretion luminosity. Gray arrows indicate the velocity field, and the gray circle encloses the planetary Hill radius. When accretion luminosity is included, the circumplanetary envelope becomes larger and the flow around it is altered.
