Caption: Figure 4.

Orbital distance as a function of companion mass consistent with the observed mid-infrared excess under the combined intrinsic and insolation heating model (Equations (1) and (2)). The black curve shows the best-fit solution corresponding to Teff,pl = 261 K, while the blue curves and shaded region indicate the range spanned by the 1σ bounds (Teff,pl = 252, 270 K).
