cm to submm view of disks

Accretion disks play a central role in the formation of low-mass stars. Recent years have seen accumulating evidence for flattened disk-like structures surrounding massive young stars. In this talk, I will present recent high resolution observations of massive disks from cm to sub-millimeter wavelength, and radiative transfer modeling of the kinematics for a better understanding of the infall and accretion around massive young stars.
