Abstract

The Polar-Ring Galaxy (PRG) candidate UGC 7388 is one of the most remarkable unstudied northern object of the family of PRGs. It is probably composed by an S0-like or spiral host and an inclined polar ring. Polar rings may be difficult to be recognized as such when they are not suitably oriented in the sky. Depending on the viewing angle, they may be mistaken or misclassified. They are formed in an encounter between two galaxies, which tend to remain together in a new and very peculiar configuration for billions of years. The two interacting components do not merge, but remain separate, essentially frozen in time. UGC 7388 shows a faint inclined ring, and so resembles a real PRG. The main goals of the proposed program are: to conduct a kinematical study employing H-alpha, [SII] and [NII] observations of this candidate Polar Ring Galaxy for redshift determination, identification of regions of induced star formation, building of rotation curves along the major and minor axes and classification of the nuclear spectra of the central galaxy (the spindle structure).
