Using high-dispersion, high-quality spectra of HD 30085 obtained with theechelle spectrograph SOPHIE at Observatoire de Haute Provence, we show thatthis star contains strong lines of the s-process elements Sr II, Y II and ZrII. Line syntheses of the lines yield large overabundances of Sr, Y, Zr whichare characteristic of HgMn stars. The Sr-Y-Zr triad of abundances is invertedin HD 30085 compared to that in our solar system. The violation of the odd-evenrule suggests that physical processes such as radiative diffusion, chemicalfractionation and others must be at work in the atmosphere of HD 30085, andthat the atmosphere is stable enough to sustain them.

The peculiar abundance pattern of the new Hg-Mn star HD 30085
