The infrared spectrum of GAM Vel.
Abstract
Infrared spectral observations of the Wolf-Rayet system Gamma Velorum in the atmospheric windows between 1.45 and 12 microns are presented. Results show an extremely rich emission line spectrum in which permitted lines of helium and carbon and forbidden lines of neon and sulfur are present, some of which have not previously been observed in any object. The relative abundances of He I/He II and C/He are estimated, and lower limits to the Ne/He and S/He abundance ratios are presented.
