Caption: Figure 3.

Photometry from SkyMapper, 2MASS, and WISE. Blue: Planck spectrum (dark blue) and the BOSZ template (lighter blue) corresponding to our measured stellar parameters for J0705+0612. Red: the best-fit disk model from M. Jura (2003) with parameters as labeled (dashed line), with the full photosphere + disk fit shown in the solid line. Inclination angle i is the angle between the disk axis and the observer’s line of sight, so ﹩\cos i=1﹩ would correspond to a face-on orientation and maximal brightness.
