Compact CO emission and no evidence of radial drift. ALMA observations of the faintest planet-forming disks in Lupus

Giulia Ricciardi, Francesco Zagaria, Anna Miotello +13

A large fraction of planet-forming disks observed with ALMA show faint CO emission, often interpreted as strong CO depletion. However, faint emission may also arise from spatially…
