| Abstract: |
Polar ring systems are `multi-spin galaxies' (Rubin 1994): different components have discrepant axes of rotation. The outer gas-rich material in polar orbit appears to be a late acquisition; it shares neither the rotation nor the symmetry axis of the early-type inner galaxy, which contains little gas and consists largely of old stars. These systems represent galaxy mergers that are not yet completed. |
