1996A&A...314..729R Photometric study of polar-ring galaxies. III. Forming rings. Reshetnikov, V.P., Hagen-Thorn, V.A., Yakovleva, V.A. Astronomical Institute of St. Petersburg State University, 198904 St. Petersburg, Russia St. Petersburg State University, 198904 St. Petersburg, Russia Received 16 January 1996/Accepted 29 March 1996 Abstract. We present the results of detailed surface photometry of NGC 3808B and NGC 6286 - two spiral galaxies with possibly forming ring- like structures rotating around major axes of the galaxies. The formation of rings in NGC 3808B and NGC 6286 being accompanied by accretion of matter on galactic disk results in some interesting gasdynamical and stellar-dynamical effects in these galaxies. One can note, for instance, peculiar rotation curve of NGC 3808B gaseous disk; strong infrared and H{alpha} emission from the galaxies; bending and flaring stellar disks in both galaxies. Our observations clearly illustrate the possibility that polar-ring galaxies may be formed as a result of matter accretion from one galaxy to another. Keywords: galaxies: interactions - photometry - galaxies: individual: NGC 3808B - galaxies: individual: NGC 6286
