Asymmetry in the protostellar system HOPS 198: Evidence for the evolution of outflow opening angle driven by density of the surrounding core
Observations and a pressure-balance model of HOPS 198 link a 2.9x difference in inferred core pressure to the 80 versus 30 degree asymmetry in outflow opening angle, supporting a density-driven evolution of outflow widths.
