Notes. Green checkmarks point out a detection, red crosses a non-detection and brackets indicate if a detection is tentative. The absence of substructures does not necessarily imply the absence of a companion/planet but may be a resolution/sensitivity effect. (a)A: obtained from ALMA continuum data in Francis & van der Marel (2020), A+G: Obtained from ALMA CO and GRAVITY data in Bohn et al. (2022).
