RY Sct is one of the best-studied B[e] stars. It is an eclipsing binary surrounded by a dusty disk, recently resolved with the Keck telescope. We attempted a 2D radiative transfer modeling of the spectral energy distribution (SED) and IR images to derive parameters of the circumstellar (CS) dust and refine the stellar properties, which have been poorly constrained. Assuming the companions' effective temperature T⋆ = 27 000 K and a distance of 1.8 kpc, we derive the system's total luminosity L⋆ = 4.2 × 10^5 L&sun;, the dusty disk's full opening angle of 26° and an inclination of 76° (nearly edge-on).
