A super-resolution analysis of the DSHARP survey: Substructure is common in the inner 30 au

The DSHARP survey evidenced the ubiquity of substructure in mm dust distribution large, bright protoplanetary discs. Intriguingly, these datasets have yet higher resolution information that is not recovered a CLEAN image. We first show intrinsic performance algorithm resolution-limited. Then analyzing all 20 sources using 1D, super-resolution code Frankenstein (frank), we accurately fit 1D visibilities to mean factor 4.3 longer baseline than Fourier transform images and 3.0 component models. This yields brightness profile for each source, identifying new interior 30 au multiple discs; resolving known gaps be deeper, wider, more structured; rings narrower brighter. Across survey, high contrast are an average 14% wider 44% deeper frank profiles relative CLEAN, 26% narrower. Categorizing into trends, find scarcity features survey's artifact power, rather rarity inner disc (or compact disc) substructure. Finally previously inferred deconvolved widths, indicating smaller alpha / St ratios local gas disc.
