(Left) Natural weighted image of continuum emission from the Atacama Compact Array (ACA). Millimeter emission is detected at the stellar position (center of the image) at 776 ± 103 μJy . The outer debris disk is seen surrounding the star at approximately 16″. The contour levels are in steps of [−2, 2, 4, 6, 8...] × the rms noise of 94 μJy beam⁻¹. The gray ellipse in the lower left corner shows the beam size, which is 7.″4 × 4.″5. (Right) Primary beam corrected, natural weighted continuum image of ϵ Eridani and the northern arc of its outer debris disk from the Atacama Large Millimeter/submillimeter Array (ALMA) 12 m array. Millimeter emission at the stellar position, 794 ± 45 μJy. The contours are in steps of [−3, 3, 6, 9...] × the rms noise of 33 μJy beam⁻¹ (primary beam corrected noise). The beam size is 1.″6 × 1.″1, as indicated by the gray ellipse in the lower left corner of the image.
