| Abstract: |
We present a survey of dense gas surrounding forming low mass stars in the Taurus and Perseus complexes. We find that the dense gas toward these stars has a two component velocity profile, consisting of a quiescent narrow line component, and a broad line component. We interpret the broad line component as outflow-disturbed dense gas, and calculate the mass and momentum flux of this material. Based on comparisons between sources of different inferred ages, we conclude that the impact outflows have on their surrounding dense cores is largest for the very youngest sources, and declines with time, perhaps because of a reduction in core/outflow coupling as an outflow excavates an exit path through the core. |
