| Abstract: | The results of a photometric investigation of the peculiar galaxy NGC 7468 are presented. Based on its integrated characteristics, NGC 7468 is a relatively small galaxy of a late morphological type, resembling the Large Magellanic Cloud (LMC). The differences of NGC 7468 from the LMC (bluer color indices, an increased luminosity, an increased H I abundance, and strong emission in the FIR range) may be related to a higher rate of star formation in it. The increased star-forming activity in the central regions of NGC 7468 and its other properties may be related to a gravitational interaction with a small neighboring galaxy, the remnants of which are now observed as a companion. |
