BVRI CCD photometry of the peculiar galaxies NGC 5605 and NGC 5665
Abstract
The paper presents the results of BVRI CCD photometry of the late-type peculiar galaxies NGC 5605 and NGC 5665 obtained on the 1.5-m telescope of the Ma danak Observatory (Uzbekistan). Regions of star formation are identified and studied. The compositions of the stellar populations in various regions of NGC 5605 and NGC 5665 are estimated using two-color diagrams. The ages of blue condensations (stellar aggregates) in the spiral arms of the galaxies are determined. It is concluded that NGC 5665 underwent an interaction with another galaxy 5×108 yr ago.
