We present evidence for localised deviations from Keplerian rotation, i.e.,velocity "kinks", in 8 of 18 circumstellar disks observed by the DSHARPprogram: DoAr 25, Elias 2-27, GW Lup, HD 143006, HD 163296, IM Lup, Sz 129 andWaOph 6. Most of the kinks are detected over a small range in both radialextent and velocity, suggesting a planetary origin, but for some of themforeground contamination prevents us from measuring their spatial and velocityextent. Because of the DSHARP limited spectral resolution and signal-to-noisein the 12CO J=2-1 line, as well as cloud contamination, the kinks are usuallydetected in only one spectral channel, and will require confirmation. Thestrongest circumstantial evidence for protoplanets in the absence of higherspectral resolution data and additional tracers is that, upon deprojection, wefind that all of the candidate planets lie within a gap and/or at the end of aspiral detected in dust continuum emission. This suggests that a significantfraction of the dust gaps and spirals observed by ALMA in disks are caused byembedded protoplanets.
