Left: polarization map in the V band of field stars around the PDS 144 system (red lines) plotted on a DSS2 Red image. The optical observed polarization for the binary components (N, north; S, south) is also indicated (yellow lines). The polarization scale is shown in the top right. Right: NIR Keck AO imaging of PDS 144 (north and south) with the PDS 144N disk resolved (adapted from P06). The jet axis position angles for both objects are indicated by black thick lines: PDS 144N = 137° ± 3°; PDS 144S = 123° ± 2° (Grady et al. 2009 and priv. comm.). The averaged intrinsic NIR polarization (H band, see Table 1) is also indicated (red arrows). The polarization scale is indicated in the bottom right.
