Insights into structure formation and volatile transport from ALMA and infrared observations of protoplanetary disks

I will present early results from an ALMA Large Program to study the initial conditions of planet formation through high resolution imaging of embedded disks. The main finding of the eDisk program is that young (< 0.5 Myr) disks around protostars do not show prominent rings, cavities or spirals. Rather, they are stirred up and are geometrically thicker than more evolved (1-3 Myr) protoplanetary disks around optically visible stars. This suggests a high level of turbulence that might reset chemistry and limit inheritance from the protostellar envelope. I will also present new observations from high resolution mid-infrared spectroscopy on Keck and IRTF that reveal conditions at au scales in the inner disk and their combination with ongoing ALMA observations of the outer disk at tens of au to understand the transport of carbon and oxygen across snowlines to the terrestrial planet-forming zone.
