Platinum and bismuth in HR 465

Abstract

Identifications in IUE spectra of HR 465 and a few other Ap stars in the magnetic sequence have been made using the method of wavelength coincidence statistics. These identifications have been supported by traditional techniques which rely on an examination of the strongest expected lines. The identification of Pt II made in a previous analysis of coude spectra has been confirmed. Lines of Ni II have also been examined, and strong to moderately-strong features are found to be present at the position of the features studied by Jacobs and Dworetsky (1982).
