31 SEPTEMBER-OCTOBER 2025 ASTRO PUBLISHING A comparison of images of protoplanetary disks in the Ophiuchus star-forming region, created with super-resolution imaging with sparse modelling versus a conventional imaging method. The resolution is indicated by the white el- lipse in the lower left corner of each panel, with a smaller ellipse denoting higher resolution. The white line in the lower right of each panel indicates a scale of 30 AU. The evolution stage of the central stars progresses from left to right, and from top to bottom in the same row.
