Abstract
We report infrared spectral observations of the Wolf–Rayet system γ Velorum. These show an extremely rich emission line spectrum in which permitted lines of helium and carbon and forbidden lines of neon and sulphur appear. Some of these lines have not hitherto been observed in any object. The data lead to estimates of the relative abundance of He I/He II and C/He (Hummer, Barlow & Storey 1982) and we present lower limits to the Ne/He and S/He abundance ratios.Keywords
