Synthetic image of a self-luminous companion (T_eff = 2000 K) with a compact circumsubstellar disk at a distance of 150 pc. The total intensity surface brightness is shownon a logarithmic scale and the lines indicate the local degree and angle of linear polarization. The spatially integrated degree of polarization is 0.24% and the angle of polarization is 0°, that is, the spatially unresolved light is linearly polarized along the minor axis of the disk.
