Illumination of the disk at different points of the binary orbit, for an equal mass central binary of e = 0.5. Each column shows the position of the binary stars (top), along with the illuminated flux received by a razor-thin disk (middle) and a flared disk (bottom). For the flared disk model, dashed lines along the disk face indicate the regions where the incoming starlight would be shadowed due to the presence of a puffed inner rim; gray and white dashed lines show shadowed regions for puff heights of 1.5h_in and 2.0h_in, respectively. Note that, for the second column, the stars are shown with a small vertical displacement to show asymmetric lighting effects close to plane crossing.
