Abstract

As a further step in our Lithium project we present results of abundance determination of some elements in the roAp star HD 60435. Possible NLTE eects were considered. Equivalent widths of spectral lines vary with rotational phase which suggests nonuniform distribution of chemical elements over the stars' surface. Large abundance dierences derived from various ions of some rare earth elements indicate their possible vertical stratication. Two spots of enhanced lithium abundance were distinguished at the magnetic poles on HD 60435 and their parameters derived. The rotational axis inclination i = 133 or 47 and surface magnetic eld Hs =3 1k G were determined for the rst time for HD 60435. The results are compared with HD 83368, the other star with lines of lithium remarkably variable in intensity and wavelength.
