Abstract: |
Since the last large sample of Galactic WC stars had been analyzed in
the middle of the 1990s, significant improvements have been achieved in
the simulation of stellar-wind spectra. We have (partly re-) analyzed all
available Galactic WC stars with the current generation of stellar
atmosphere models computed with the Potsdam Wolf-Rayet (PoWR) code. In
contrast to previous results, the obtained stellar parameters now show
a close correlation with the WC subtype. The stellar temperatures form
a sequence from 45 kK (WC9 subtype) to about 120 kK (WC4). For those
stars with known distance, we also derived luminosities using
flux-calibrated spectra and photometry. |
