  As a result of bidimensional spectroscopy of the central parts of two nearby
lenticular galaxies, NGC 1023 and NGC 7332, undertaken with the Multi-Pupil
Field Spectrograph of the 6m telescope of the Special Astrophysical
Observatory, their chemically decoupled stellar nuclei are found to be
substantially younger than the surrounding bulges: the mean age of the nuclear
stellar populations is 7 billion years in NGC 1023 and 2.5 +/- 0.5 billion
years in NGC 7332. The morphological analysis undertaken by Seifert and Scorza
(1996) for NGC 7332 and by us for NGC 1023 has revealed a existence of separate
circumnuclear stellar disks with the radius of 80 pc in NGC 1023 and of 400 pc
in NGC 7332; probably, the intermediate-age stellar populations are related to
these structures.
