| Description | Massive outflows are known to drive a special chemical complexity due to thestrong shocks they produce in the surrounding molecular material. Hydrides are key ingredients of interstellar chemistry since they are theinitial products of chemical networks that lead to the formation of morecomplex molecules. Given their small reduced masses, their rotational lineslie at short sub-mm wavelengths, which are almost unobservable from theground. With the HIFI instrument on board of the Herschel satellite it is nowpossible to observe the strongest transitions of light hydrides, in particularH2O but also the reactive ions OH+ and H2O+, which are thought to play acrucial role in the formation of OH and H2O. HIFI early results revealed thatindeed water and its cation H2O+ are abundant components of theinterstellar medium. The additional HIFI detection of OH+ is an importantconfirmation of the gas-phase route of water. Although key programs havetargeted few massive sources to map the water distribution, acomprehensive study including other important hydrides such as OH+ and H2O+,and covering sources in different evolutionary phases, has notbeen provided yet.This project proposes a dedicated study of water and related hydrides (H2O+ andOH+) in massive protostellar outflows in order to: a) trace the waterdistribution throughout the different evolutionary phases of massive starformation, b) determine the contribution of water emission in the energy lostby shocks, and c) unveil the role of ions such as OH+ and H2O+ in the production of water. |

| 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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
