Query: Study of Star-Forming Regions in the Peculiar Galaxies NGC 660, NGC
  1512, NGC 4395, and NGC 4618   The star-forming regions (SFRs) in the peculiar galaxies NGC 660, NGC 1512,
NGC 4395 and NGC 4618 are studied. The relationships between such
characteristics of star forming regions as UV, nearand far-IR fluxes, as well
as in the Halpha and HI lines, surface brightness in these ranges, and the
scatter of the radial velocities of ionized and neutral hydrogen are
considered. It is shown that in all the galaxies considered, the IR fluxes from
SFRs are less than in the "normal" galaxies, but for different reasons: in the
galaxies with signs of recent interaction NGC 660 and NGC 1512, this is due to
the low surface brightness of SFRs; in the lopsided galaxies NGC 4395 and NGC
4618, the low brightness of SFRs in the infrared range is due to their compact
size. These differences indicate that the star formation process depends not
only on the morphological type of a galaxy, but also on many other factors.
