We explore the dynamical structure of the protoplanetary disks surrounding HD 163296 and MWC 480 as part of the Molecules with ALMA at Planet-forming Scales (MAPS) large program. Using the J = 2–1 transitions of 12CO, 13CO, and C18O imaged at spatial resolutions of ∼0.″15 and with a channel spacing of 200 m s−1, we find perturbations from Keplerian rotation in the projected velocity fields of both disks (≲5% of the local Keplerian velocity), suggestive of large-scale (tens of astronomical units… Expand
