Polar-ring Catalog
(PRC)
(1990 catalog of polar-ring galaxies)
The Polar-ring Catalog is
a 1990 list of polar-ring galaxies.
A polar-ring galaxy has
a ring of gas and stars orbiting at a considerable angle to
its galactic plane, often near perpendicular,
coming close to crossing the galaxy's poles.
Such galaxies are assumed to form from
interactions of two galaxies.
They are of particular interest in what they
might reveal about the dynamics of galaxies
and of galactic halos.
