Polar-ring galaxies are photometrically and kinematically decoupled systemswhich are highly inclined to the major axis of the host galaxy. These objectshave been explored since the 1970s, but the rarity of these systems has madesuch study difficult. We examine a sample of over 18,362 galaxies from theSloan Digital Sky Survey (SDSS) Stripe 82 for the presence of galaxies withpolar structures. Using deep SDSS Stripe 82, DESI Legacy Imaging Surveys, andHyper Suprime-Cam Subaru Strategic Program, we select 53 good candidategalaxies with photometrically decoupled polar rings, 9 galaxies with polarhalos, and 34 possibly forming polar-ring galaxies, versus 13 polar-ringcandidates previously mentioned in the literature for the Stripe 82. Ourresults suggest that the occurrence rate of galaxies with polar structures maybe significantly underestimated, as revealed by the deep observations, and mayamount to 1-3% of non-dwarf galaxies.
