Star-forming complexes in the polar ring galaxy NGC660
  Galaxies with polar rings consist of two subsystems, a disk and a ring, which
rotate almost in orthogonal planes. In this paper, we analyze the parameters
characterizing the composition of the interstellar medium and star formation in
star-forming complexes, belonging to a polar ring galaxy NGC660. We show that
star-forming regions in the ring of the galaxy are distinctively different from
those in the galaxy disk. They possess substantially lower infrared
luminosities, indicative of less dust mass in these regions than in a typical
disk star-forming region. UV and H$\alpha$ luminosities also appear to be lower
in the ring, probably, being a consequence of its relatively recent formation.
