The ultraviolet spectrum of Zeta Puppis.
Abstract
Spectral plots are presented for high-resolution scans of the O4 If star Pup between 907 and 3196 A obtained with the Copernicus satellite. The nominal resolution is 0.05 A from 907 to 1443 A, 0.10 A from 1426 to 1650 A, and 0.4 A from 1408 to 3196 A. Wavelengths and equivalent widths are tabulated for all the photospheric absorption lines. These spectra show that He 1, He II, C iv, N m, N iv, 0 in, 0 iv, Si iv, P iv, P V, S iv, and Fe V are present or probably present in the photosphere, and N V, 0 V, Ne 111, Si m, S iii, Cliv, Cr V, and Mn iv are possibly present, whereas C II, C Hi, 0 Vi, Ne iv, Mg in, Mg iv, Al iv, Si n, P iii, Cliii, Ar iv, Ca m, Ti iv, V iv, V V, Cr iv, Mn V, Fe iii, Fe iv, Ni iv, and Ni V probably are absent. The Lw lines between 1000 and 1375 A have an average FWHM of 413 + 90 km 1, which corresponds to V sin i = 260 + 60 km 1 in a plane-parallel non-LTE model.
