Dereddened broadband visible and near-infrared SED of HD 139614 (diamond), along with its MIDI and Spitzer total flux spectra. We also show the tabulated synthetic Kurucz spectrum (T_eff = 7750 K, log g = 4.0, Fe/H = −0.5) that represents the central star contribution best (see Table 1). Overplotted is the best-fit solution of the one-component model (blue solid line) in the medium-density case, and of the two-component disk model (red solid line) in the high-density case.
