Images of the 7 mm continuum emission from six debris disks detected in the ATCA sample. Contour levels are in steps of 2 × rms for all images, except AK Sco (lower center), where contours are in steps of 4 × rms (characteristic rms ∼14 μJy). The ellipse in each lower left corner indicates the synthesized beam size. The star symbol marks the position of the stellar photosphere. The dashed gray line indicates the position angle of the disk determined from previous optical, near-infrared, or millimeter imaging and listed in Table 1.
