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. ...

... In this case, the main vortex in the Benard cell is decomposed into smaller ones as a result of ten perioddoubling bifurcations. It is shown that the resulting turbulence is coherent and determinate; the fractal character (local selfsimilarity) of its spectrum is found. ... It is shown that the real atmospheric turbulence is the result of mixing of different coherent structures. ...
