Study of the structure and kinematics of the NGC 7465/64/63 triplet
  galaxies
  This paper is devoted to the analysis of new observational data for the group
of galaxies NGC 7465/64/63, which were obtained at the 6-m telescope of the
Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS)
with the multimode instrument SCORPIO and the Multi Pupil Fiber Spectrograph.
For one of group members (NGC 7465) the presence of a polar ring was suspected.
Large-scale brightness distributions, velocity and velocity dispersion fields
of the ionized gas for all three galaxies as well as line-of-sight velocity
curves on the basis of emission and absorption lines and a stellar velocity
field in the central region for NGC 7465 were constructed. As a result of the
analysis of the obtained information, we revealed an inner stellar disk (r ~
0.5 kpc) and a warped gaseous disk in addition to the main stellar disk, in NGC
7465. On the basis of the joint study of photometric and spectral data it was
ascertained that NGC 7464 is the irregular galaxy of the IrrI type, whose
structural and kinematic peculiarities resulted most likely from the
gravitational interaction with NGC 7465. The velocity field of the ionized gas
of NGC 7463 turned out typical for spiral galaxies with a bar, and the bending
of outer parts of its disk could arise owing to the close encounter with one of
galaxies of the environment.
