| Description | We would like to perform a systematic line survey of the prototype carbon-rich AGB star IRC+10216. This object is particularly rich in carbon chain molecules and radicals and shows an impressive HCN spectrum in the submillimeter and far-infrared domains. The coverage of the HIFI instrument will permit to characterize the complete molecular content of the innermost zones of the envelope and complement the low frequency observations available from ground-based radio observatories. The sensitivity of the survey is such that at 1 THz we approach the detection limit of a ground based telescope such as the 30m IRAM radiotelescope after several hours of observing time. The 1500 GHz we want to cover requires 45 hours of GT observing time. A line survey covering 100 GHz with the 30m IRAM radiotelescope at an equivalent sensitivity requires several weeks of observing time. |

| 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. |
