The IUE absorption spectrum of the nucleus of NGC 246: mostly C IV and O VI.

FEIBELMAN W.A.

Abstract (from CDS):

We present a list of more than 140 absorption features and their equivalent widths for the central star of the planetary nebula NGC 246 as observed in the wavelength range lambda-1169-lambda 2000. High signal-to-noise ratios are achieved by coadding nine high-dispersion SWP spectra, representing a total of nearly 22 hrs observing time. The IUE spectrum is dominated by strong absorption lines, or blends, of O VI and C IV. Other ions include N V, O V, Si IV, Fe VI, Fe VII, and Ne VII, plus interstellar absorption lines. The only feature to display a P Cygni profile is the C IV resonance doublet from which a terminal wind velocity of 4120 ± 200 km s^-1 is derived.
