| Abstract | The H I-rich S0/a galaxy NGC 7013 was mapped in the H I line with a spatial resolution of 25arcsec×50arcsec (α×δ) and a velocity resolution of 33 km s-1. On the large scale, the H I distribution may be described by two rings, the larger at the edge of the optical disc and the smaller possibly associated with the inner stellar ring in the galaxy. The H I surface density in the disc itself is very low. The authors suggest that NGC 7013 is a former late-type spiral in which the H I density in the disc has become too low for significant star formation. The presence of the outer H I ring in the galaxy makes it unlikely that this is due to external sweeping. |
