Title: Herbig-Haro Jets and their Energy Sources

Speaker: Bo Reipurth

Abstract: Herbig-Haro jets have in recent years emerged as powerful tools for understanding the activity of newborn embedded stars. It has been established that HH jets can extend over many parsecs, and they can therefore deposit energy and momemtum into regions of their nascent clouds far from their birthsite. High resolution studies with the Hubble Space Telescope have enabled us to understand the detailed structure of HH jets, and images taken at several epochs have provided kinematic information on the jet flows, as well as insight into the time-dependent behavior of the shocks involved. The link between HH jets and molecular outflows will be discussed, as well as the relation between jets and accretion disk events in their driving sources.
