- Аннотация: The previously performed study of galaxies residing in low density environment revealed a number of objects which deviate significantly from the "standard" "metallicity-luminosity" relation. These objects, with significantly reduced metallicity for their luminosity, are represented mainly by faint dwarf galaxies. But among such objects there are also a few galaxies of the intermediate luminosity. They appeared to be the late-type galaxies with regions of intense star formation on their periphery. We compiled a sample of such unusual objects for their further investigation. Our hypothesis is that their reduced metallicity along with apparent peculiar morphology might be caused by the accretion of the external gas onto these galaxies. To examine this hypothesis we use Fabry-Perot interferometer data in H-alpha line. Here we present first results of our study.
