We propose to use the SPIRE-FTS to obtain the spectrum of a 14 young stellar objects that have been observed with PACS and SPIRE in imaging. These YSOs are highly embedded sources that have not been observed before at wavelengths shorter than 100 micron. We propose to use the FTS to ascertain their physical properties (mass and age) using chemical tracers such as the ones that trace outflows and shocks. These YSOs span a large range of luminosity, evolutionary stage and mass. The obtained FTS spectra will constitute the first existing far IR spectral database of YSOs.

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.
