2D surface density distribution for the isothermal disk model near the final state of its evolution. The gray dots refer to the positions of the two binary stars and the planet. The Roche lobe of the system of the secondary star and planet are also shown. The blue dashed line refers to the orbit of the planet, and the blue arrow points to the periapse of the planetary orbit. The red arrow points to the periapse of the inner, eccentric disk, while the green arrow points to the periapse of the binary. The white dashed circle refers to the observed semi-major axis of the planet with a radius of 1.09 AU.
