Further observations of the peculiar hot helium-rich degenerate KPD 0005 + 5106

KPD 0005 + 5106 observations including high- and low-resolution IUE and Voyager UV spectra, high-resolution spectra at optical wavelengths, and a low-resolution spectrum at red wavelengths are presented. The only detected transitions from a heavier element assignable to the stellar photosphere is the N V 1240 A doublet; hydrogen and some probable CNO ions are also detected in the emission. It is suggested that the detected nitrogen is most likely due to selective radiative acceleration processes.
