|Abstract:||Abstract—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, near- and far-IR fluxes, as well as in the Hα 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. © 2020, Pleiades Publishing, Ltd.|

Makarov for useful discussions. This work is based in part on observations made with the Spitzer Space Telescope, which was operated by the Jet Propulsion Laboratory, California Institute of Technology under a contract with NASA and Herschel Space Observatory that is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA. The astronomical database HYPERLEDA (http://leda.univ-lyon1.fr) was used in the work. The research was supported by Russian Foundation for Basic Research as part of the science project no. 19-32-50063. The work is based on the use of observations from 6‑meter telescope of SAO RAS, supported by the Ministry of Science and Higher Education of the Russian Federation (agreement no. 05.619.21.0016, project ID RFMEFI61919X0016).|
