The C/N Ratio in WN and WC Stars
Published online by Cambridge University Press: 14 August 2015
Extract
We present new determinations of the C/He, N/He and C/N ratios in 6 WN and 4 WC stars, resulting from a Sobolev analysis of new IUE UV line measurements in these species. Through improved observations of more stars, the present work extends an earlier, UV-based, study carried out by Willis & Wilson (1978, WW), which gives details of the Escape Probability Modelling (EPM) utilised. Full details of the current IUE observations, measurements and modelling will appear in Monthly Notices: here we summarise the results. Table 1 lists the ten WR stars currently studied — all were observed at low resolution and the brightest eight at high resolution.
