The velocity characteristics of WR stellar winds
Abstract
The stellar winds of hot early-type stars are characterized spectroscopically by the presence of P-Cygni profiles. The WR stars have more developed stellar winds than OB stars, supporting higher particle densities at larger distances from the stellar 'photosphere'. The present investigation is concerned with an analysis of the UV (and visible) P-Cygni profiles observed in 10 WR stars. The UV spectroscopy was obtained using the high resolution International Ultraviolet Explorer (IUE) mode in the wavelength range from 1150 to 3250 A. Attention is given to details regarding the velocity measurements, the H/He ratio, and stellar wind terminal velocities.
