Title Oxygen abundances in carbon-type Wolf-Rayet stars from PACS scan spectroscopy

Author crowther, p.
Description We seek 13.6 hours of spectral scans of the [OIII] 88 micron fine-structure line with PACS for a sample of Milky Way carbon and oxygen sequence Wolf-Rayet stars. The proposed observations will: (i) enable reliable oxygen abundances to be determined for WC stars for the first time, to test evolutionary predictions; (ii) refine the degre of clumpig in the outer stellar winds of these stars derived from existing ISO-SWS or Spitzer-IRS datasets.

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.
