ARKS discs detected in scattered light. The observations were made using the VLT – SPHERE instrument, unless otherwise specified. The discs denoted by ‘I’ were observed in total intensity, whereas the ones with ‘pI’ were observed in polarised light. The white line at the bottom right corner represents an angular scale of 0.5″, with the corresponding projected distance in au labelled in each panel. The white contours show the ALMA continuum observations, with three contour levels at a S/N of 3, 5 and 7 σ (see the corresponding ALMA image in Paper I Fig. 3 Marino et al. 2026b, for each disc). The white ellipse at the bottom left represents the ALMA image resolution and the white cross is the stellar position from GAIA DR3. For HD 131835, we show the image post-processed with the PACO algorithm (Flasseur et al. 2018), best highlighting the two rings. In all panels, North is up, East to the left.
