De-reddened spectral energy distribution of Wray 15-788. The blue curve shows a Coelho stellar model (Coelho 2014) with T_eff = 4250 K, log (g) = 4.5, [Fe/H] = 0, [α/Fe] = 0, and A_V = 0.74 that isfitted to the red data points from the APASS, Gaia, 2MASS, and DENIS photometry. The gray squares denote flux measurements from WISE, IRAS, AKARI/FIS, and AKARI/IRC, and the brown triangles provide upper limits from IRAS. Three blackbodies with T_{dust, 1} = 969 K, T_{dust, 2} = 83 K, and T_{dust, 3} = 25 K were simultaneously fitted to the green data points that denote the object’s far-infrared excess, corrected for stellar contamination. The individual blackbody functions are indicated by the dashed gray lines, whereas their sum is presented by the solid orange curve.
