These disks host dust-depleted inner regions, possibly carved by massive planets, and are of prime interest to study the imprints of planet-disk interactions. While at moderate angular resolution they appear as a broad ring surrounding a cavity, the continuum emission resolves into multiple rings at a resolution of ~60$\\times$40 mas (~7.5 au for LkCa 15, ~6 au for J1610) and ~$7\\,\\mu$Jy beam$^{-1}$ rms at 1.3 mm.
