Origin and impact of protostellar outflows

Determine the physical origin of protostellar outflows (including collimated jets and wider molecular outflows) and quantify their impact on protoplanetary disk evolution and planet formation processes.

Background

The paper investigates DG Tau B, a Class I protostar with a structured disk and rotating CO outflow, as a prime system to paper outflow origins and their consequences for disk evolution. The authors emphasize that understanding whether outflows arise from mechanisms such as magnetohydrodynamic disk winds or swept-up envelope material, and how they regulate mass and angular momentum in disks, remains pivotal for models of disk evolution and planet formation.
