Quantitative analysis of WC stars: Constraints on neon abundances from ISO/SWS spectroscopy [PDF]

, 2000
Neon abundances are derived in four Galactic WC stars -- gamma Vel (WR11, WC8+O7.5III), HD156385 (WR90, WC7), HD192103 (WR135, WC8), and WR146 (WC5+O8) - using mid-infrared fine structure lines obtained with ISO/SWS.
