PACS range spectroscopy will be performed around the 69 micron forsterite dust feature of evolved stars. With the spectral resolution and sensitivity of PACS we will be able to fit the profile of the forsterite feature which is verysensitive to temperature. By studying the forsterite feature in a wide range of evolved stars and from different populations (includingGalactic Bulge and LMC) we want to determine the role of forsterite in the dust formation in the circumstellar environments.

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.
