H. ; Snell, R. L. ; Goldsmith, P. F. ; Strom, S. E. ; Strom, K. M. Abstract Dense gas associated with seven regions of recent star formation and outflow activity has been studied using primarily observations of CS J = 2-1 emission. It is found that the distribution of the dense gas is often elongated, yet shows no preferred orientation with respect to the local magnetic field, rotational axis of the core, or outflow direction. Thus, it is unlikely that large (10 to the 17th cm) interstellar objects can be responsible for the focusing of stellar winds into collimated jets. The position of the embedded stellar object in all seven sources is at, or near, the maximum of CS emission. If stars acquire a peculiar velocity with respect to the cloud, the observed positional coincidence suggests that embedded stars are very young, and that outflow activity occurs within the first 100 kyr of the star's lifetime.
