Scientific paper

The results on the properties of the stellar population of the central parts in nearby lenticular galaxies which are obtained with the multipupil fibre field spectrograph of the 6m telescope during the last 10 years are reported. Most S0 galaxies show prominent signs of nuclear star formation bursts some 3 5 Gyears ago; the unresolved nuclei are on average much younger than the surrounding bulges. Also the present author found that there is a link between the mean luminosity-weighted stellar population ages and the galaxy environment; in dense environments the stellar populations are older on average, both in the nuclei and in the bulges.
