The IUE spectrum of the binary nucleus of the planetary nebula NGC 1514.

FEIBELMAN W.A.

Abstract (from CDS):

Archival IUE low-dispersion spectra and the first ultraviolet high-dispersion spectrum of the binary nucleus of NGC 1514 have been analyzed. Both SWP and LWR low-dispersion spectra show variability by as much as a factor of two in the continuum level between the years 1978 and 1989. Weak P Cygni features for OV lambda 1371 and C IV lambda 1549 yield terminal wind velocities of -105 plus or minus 25 and -960 plus or minus 150 km s-1, respectively. No nebular emission lines were detected, but several photospheric and interstellar absorption features were observed. Absorption lines of Fe VII are suspected. The He II lambda 1640 absorption line has a radial velocity of +49 plus or minus 3 km s-1 and is in good agreement with optical data. The peculiar energy distribution of the SWP continuum for NGC 1514 can be synthesized by the coaddition of spectral type A0 - A3 III plus hot subdwarf IUE spectra.
