A QUANTITATIVE-ANALYSIS OF THE PROTOTYPE [WCL] STAR CPD-56-DEGREES-8032

We present a detailed, quantitative study of the standard [WC10] Wolf- Rayet central star CPD-56 degrees 8032 based on new high resolution AA T UCLES observations and the Hillier (1990) WR standard model. Our ana lysis of CPD-56 degrees 8032 gives the wind properties (T=34500K, lg (L/L.)=3.8, lg (M/M.a(-1))=-5.4, v(infinity)=225 km s(-1)) and chemist ry (C/He=0.5, O/He=0.1, by number), the latter suggesting an intimate relationship with the O VI PN central stars and the PG 1159-035 object s. A comparison between the wind properties of CPD-56 degrees 8032 and Sk-66 degrees 40 (WN10) indicates that low excitation, low wind veloc ity WR winds are common to both low mass PN central stars (WC sequence ) and high mass post-LBV's (WN sequence).
