What is the significance of outflows ejected from a protostar’s poles during its dynamic stage?

Answer

They carve out cavities and halt further immediate accretion onto the core

During the dynamic protostar stage, violent outflows of material are often ejected from the poles, which serves to carve out cavities in the surrounding cloud and temporarily stop further mass from immediately accreting onto the central core.
