Abstract (from CDS):

We present the results of stellar photometry of the polar-ring galaxy NGC 660 using the Hubble Space Telescope's archival data obtained with the Wide Field Planetary Camera 2. The final list of the resolved stars contains 550 objects, a considerable part of which are blue and red supergiants belonging to the polar ring. The analysis of the Colour-Magnitude Diagram for polar ring stars shows that it is best represented by the isochrones with metallicity Z=0.008. The process of star formation in the polar ring was continuous and the age of the youngest detected stars is about 7Myr.
