Title Measurements of the Atomic Carbon Isotope Ratio in Evolved Stars

Description We propose to use Herschel-HIFI to observe the atomic carbon isotope ratios of evolved stars. The sample of circumstellar envelopes to be studied are being observed by the HIFISTARS program, where the oxygen isotope ratios will be measured via H2O. The proposed observations will allow us to determine the carbon isotope ratio in various types of stars (C-rich, O-rich, and S-type) as well as constrain chemical fractionation that may occur in the outer envelopes of these objects and-or provide insight into other nucleosythetic processes that may alter the CNO-isotopic abundances. The data in this program are complimentary and will employ the results obtained from the HIFISTARS program.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
