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