| Description | The aim of the present proposal is to detect and understand how theinterstellar medium (ISM) changes due to star formation. To do this weintend to perform a (large scale) spectral survey using the SPIRE spectrometer. The main idea isto scan with the SPIRE FTS along gradients of increasing temperature,density and star formation activity, e.g. from the edge of a star formingregion to its centre. Making sure to include regions of different levelsof star formation activity and clump/core density, we aim to probe theISM in its different phases and see what are the r^ant changes inits physical properties. Starting from the assumption that allstars in a star formation region are formed from the samematerial but not at the same time, we wish to probe the physicalconditions of the ISM from a low-activity region to a region where starsare already formed. In this way we will be able to directly relate thechanges in the ISM to star formation activity. |

| 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. |
