Abundances in Przybylski's star

We have derived abundances for 54 elements in the extreme roAp star HD 1010 65. ESO spectra with a resolution of about 80 000, and S/N of 200 or more w ere employed. The adopted model has T-eff=6600 K, and log(g)=4.2. Because o f the increased line opacity and consequent low gas pressure, convection pl ays no significant role in the temperature structure. Lighter elemental abu ndances through the iron group scatter about standard abundance distributio n (SAD) (solar) values. Iron and nickel are about one order of magnitude de ficient while cobalt is enhanced by 1.5 dex. Heavier elements, including th e lanthanides, generally follow the solar pattern but enhanced by 3 to 4 de x. Odd-Z elements are generally less abundant than their even-Z neighbours. With a few exceptions (e.g. Yb), the abundance pattern among the heavy ele ments is remarkably coherent, and resembles a displaced solar distribution.
