1987ApJ...314..457V H I maps of S0 galaxies with polar rings J. H. van Gorkom, Paul L. Schechter, and Jerome Kristian Abstract. VLA maps in the 21 cm line of neutral hydrogen have been obtained for three S0 galaxies with polar rings, and an upper limit on H I has been obtained for a fourth system. Polar rings span a continuum, ranging from those in which the H I seems to be in a relatively stable configuration, producing stars throughout its extent, to those in which the H I is very asymmetric, with stars forming only at the inner edge of an H I disk. A deep CCD image of MGC -5-7-1 shows arcs and filaments, some of which coincide with the likewise chaotic H I. If the system formed as the result of the merger of a gas-rich system with an S0 galaxy, the gas-rich system must have included considerable numbers of stars. Key words: ASTRONOMICAL MAPS, GALACTIC STRUCTURE, HYDROGEN CLOUDS, NEBULAE, CENTIMETER WAVES, HALOS, RADIAL VELOCITY, RADIO GALAXIES, RING STRUCTURES
