| Description | This is a resubmitted priority 2 OT1 programme to scan OIII 88micron with PACS for a sample of Milky Way carbon and oxygen sequence Wolf-Rayetstars. The proposed observations, requiring 7.7hr will: (i) enable reliableoxygen abundances to be determined for WC stars for the first time, testingevolutionary predictions; (ii) refine the degree of clumping in the outerstellar winds of these stars derived from existing ISO/SWS or Spitzer/IRSdatasets. The requested line spectra are unique to PACS and cannot beacquired with another instrument for these targets. |

| 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. |
