Talk Title: 
Reimagining Protostellar Disk Formation and Evolution
Event description: 


The canonical picture of how planetary systems - like our own Solar System - may form has traditionally considered the onset of planet formation to occur in several million year old gas-poor dusty disks. Recent higher resolution interferometric surveys of these disks have found that planet formation is likely well underway in these systems, suggesting that these objects can not be used as the fiducial initial conditions for planet formation processes. Looking to earlier embedded protostellar systems, whose dynamical and chemical environment is dominated by the infall of star-forming material, one can argue that the star-forming environment plays an important role at this stage. In this talk, I will review our theoretical understanding of disk formation and evolution, discuss the evidence for an updated model of protostellar infall onto disks, and present recent modeling efforts to investigate the viability of these earlier phase objects as sites of planet formation.
