Polar-bulge galaxies
  Based on SDSS data, we have selected a sample of nine edge-on spiral galaxies
with bulges whose major axes show a high inclination to the disk plane. Such
objects are called polar-bulge galaxies. They are similar in their morphology
to polar-ring galaxies, but the central objects in them have small size and low
luminosity. We have performed a photometric analysis of the galaxies in the g
and r bands and determined the main characteristics of their bulges and disks.
We show that the disks of such galaxies are typical for the disks of spiral
galaxies of late morphological types. The integrated characteristics of their
bulges are similar to the parameters of normal bulges. The stellar disks of
polar-bulge galaxies often show large-scale warps, which can be explained by
their interaction with neighboring galaxies or external accretion from outside.
