Description We propose to resolve the origin of the strong [OI] 63micron and [CII] 158 micron emissions, within protostellar jet-outflow sources, detected by ISO LWS, and use it as a diagnostic of the shock conditions. Both [CII] and [OI] emission are useful diagnostics of the postshock gas, and [OI] is an efficient coolant in the high velocity dissociative shocks. Though [CII] is less important as a coolant in the shocks, its high intensities make it an ideal probe for Herschel because of HIFIs high spatial and velocity resolution which can answer where, within a jet and wind driven environment filled with shocks and outflow cavities, such strong emissions originate. In this proposal we use the PACS and HIFI spectral line mapping of shocks in 4 representative jet-outflow sources to study their spatial and velocity structures and their association with the jets and outflows, and the entrained regions. All these jet outflow targets have strong [OI] and [CII] detections by ISO LWS and contain atomic and ionic and molecular hydrogen jets; two were selected for the presence of wide angle outflow cavities; and two were selected for their star-forming and external FUV environments. These observations will characterize the components of the [OI] and [CII] associated with the shocks and outflows and serves as templates for understanding the ISO detections in a larger sample and using them as probes in future.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
