DETERMINING HOT STAR WIND TERMINAL VELOCITIES FROM LOW-RESOLUTION IUE DATA.
221 - 224.
Empirical relations are provided which enable consistent determinations of wind terminal velocities for hot stars where only low-resolution IU E spectra are available. The calibrations are based on terminal velocities derived from the violet limit of 'black' absorption troughs seen in high-resolution IU E spectra of saturated wind lines of hot stars, and the corresponding wavelengths of the absorption minima and emission peaks in low-resolution spectra of C IV lambda 1550 and N V lambda 1240 P Cygni profiles of the same stars. The relations may be applied to low-resolution IU E data of extragalactic WR and OB stars, and the nuclei of planetary nebulae.
