Spectral energy distribution of CoRoT 223992193 (cyan points) based on the magnitudes listed in Table 2, plus upper limits in the far-IR (cyan arrows). Left: the grey line and magenta triangles show the best-fit two naked photospheres model. Right: the black line and magenta triangles show the best-fit two naked photospheres model with a small amount of hot dust in the inner cavity of the circumbinary disk (see text for details). The stellar and hot dust terms are shown separately as the grey solid and dashed green lines, respectively. Also shown for completeness, but not used in the fit, is the expected emission from a razor-thin circumbinary disk extending down to 22 R_⊙ (brown dot-dashed line), which is illuminated by the central star and heated by the gravitational potential energy released from accretion with Ṁ = 10^-11 M_⊙ yr^-1.
