Resonance line-profiles in galactic disk UV-bright stars.
Abstract
The authors have made a comparative analysis of UV resonance line-profiles in O-type stars members of young clusters and OB associations, with those of hot stars located away from sites of recent star formation (including "runaway" stars). The resonance line-profiles are found to be generally dominated by stellar winds that appear to depend mainly on the surface gravity and temperature of the star, and not on its mass. The use of only the largest stellar wind velocity detectable in the resonance lines as a stellar population indicator, is disputed.
