Photometric structure of polar-ring galaxies.
Abstract (from CDS):
The results of B, V, R surface photometry of three polar-ring galaxies (PRGs) - A0017+2212, UGC 1198, UGC 4385 - are presented. The data were acquired at the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. It was shown that all three galaxies are peculiar late-type spirals in the state of ongoing interaction or merging. We discuss available photometric properties of the PRGs with spiral hosts and consider the Tully-Fisher relation for different types of PRGs. In agreement with Iodice et al. (2003ApJ...585..730I), we have shown that true PRGs demonstrate ∼1/3 larger maximum rotation velocities than spiral galaxies of the same luminosity. Peculiar objects with forming polar structures satisfy, on average, the Tully-Fisher relation for disk galaxies but with large scatter.
