Caption: Figure 1.

Images of the 9 mm continuum emission from the six debris disks detected in the VLA sample. Contour levels are in steps of [2, 3, 4, 6] × rms for all images, except HD 141569 (lower center), where contours are in steps of 3 × rms (characteristic rms ∼5 μJy). The white contours in the AU Mic image (lower right) mark the subtracted stellar component in steps of ﹩[10,20,40,80,160]﹩ × rms. 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.
