THE H II REGIONS OF HOLMBERG II

Calibrated H-alpha and continuum CCD frames are used to measure the emission-line luminosities and mophological characteristics of 82 H II regions in the dwarf irregular galaxy, Ho II, in the M81 group. The assemblage of H II regions is statistically normal: the luminosity function fits a power law with -1.70 and the size distribution is roughly exponential with a scale length of 85 pc. An unusally large number of H II regions show ring structures, a fact that may be correlated with the galaxy's unusual H I structure (Puche et al., 1992).
