The IUE spectrum, electron density, and terminal wind velocity of the "O VI sequence" planetary nebula NGC 5315

Extensive archival and new IUE data obtained during the last (19th) year ep isode of the "O VI sequence" planetary nebula NGC 5315 and its central star have been analyzed. A large number of high-excitation emission lines have been identified, and their fluxes were determined. These yield electron den sities from C III], Si III], and N III], and terminal wind velocities from C IV lambda 1549 low- and high-dispersion spectra. The values are quite hig h, in the range of log N-e = 4.9 +/- 0.1 cm(-3) from C III] and Si III] dia gnostics, and terminal wind velocities are in the range of - 3600 +/- 100 k m s(-1).
