Scientific paper

The authors have searched for environmental density-related modifications of basic optical properties (luminosities, sizes, axial ratios, and colours) of galaxies belonging to Geller and Huchra's (1983) groups. They have found that the broad maxima of the distributions of luminosities and diameters of spirals and the whole corresponding distributions of lenticulars tend to move to lower values as one goes to groups of high compactness, whereas the luminosity-diameter relationship of spirals tends to become flatter. No colour and axial ratio differences between galaxies of high- and low-compactness groups have been detected.
