STUDIES OF THE INTEGRATED COLOR INDEXES OF INTERACTING GALAXIES

The results of B, V, and I photometry of a sample of 24 relatively nea rby (z less than or equal to 0.05) interacting galaxy systems are anal yzed. It is confirmed that the scatter of the color indices on two-col or diagrams is greater for interacting galaxies than for isolated gala xies. The two galaxies making up binary interacting systems have corre lated color indices (the Holmberg effect). The integrated photometric characteristics for the tidal tails of ten galaxies are determined. Th e sum of the characteristics of these tidal tails - their color indice s, surface brightnesses, and neutral hydrogen content - are similar to those for low-surface-brightness dwarf galaxies. This provides eviden ce for the possible formation of dwarf galaxies in tidal structures in interacting galaxies.
