Line identifications and preliminary abundances from the red spectrum of HD 101065 (Przybylski's star) * **
Received 19 June 1998 / Accepted 5 August 1998
We have made a line identification list and derived preliminary abundances for the extreme peculiar star HD 101065 (Przybylski's star), based on a spectrum recorded at ESO with the CASPEC spectrograph. The line list covers the range 5445-6587 Å. We find iron to be mildly deficient, possibly not as much as an order of magnitude, while the lanthanide rare earths are enhanced by some 4 dex. Abundances rather like this are found in the hotter Ap stars. However, spectra of the latter are quite different in appearance from HD 101065. Insight into how this can be is illustrated from a synthesis of the region containing the strong iron lines , 4404, and 4415. Advantage is taken of the achieved line identifications to determine the longitudinal magnetic field of the star from the analysis of the Nd lines of its spectrum: G.
