| Abstract | High-resolution kinematic data have been obtained for the small Magellanic irregular galaxies DDO 125 and Ho II through observations in the 21-cm H I line. The two galaxies appear to have well-ordered velocity fields which, except at the extremities of the disk, are describable in terms of solid-body rotation. Mass models based on Gaussian distributions are devised for both galaxies; a mass of five times 10 to the eighth power solar masses is established for each galaxy. For the sake of comparison, large-scale features of other irregular galaxies are also considered. |
