YOUNG STELLAR NUCLEI IN LENTICULAR GALAXIES: NGC 5574 AND NGC 7457 1 O. K. Sil'chenko 2 Sternberg Astronomical Institute, Universitetsky Pr. ... The compact nuclei of the galaxies appear to be chemically distinct: in NGC 5574 the nucleus is distinguished by a higher than solar irontomagnesium ratio, and in NGC 7457 a drop of mean stellar met allicity by a factor of 2 exists between the nucleus and the bulge. ... The bulges in NGC 5574 and NGC 7457 have rather young stellar populations. ...
