1990PASP..102.1245H THE H II REGIONS OF IC 1613 PAUL HODGE, MYUNG GYOON LEE, AND MARK GURWELL Department of Astronomy, University of Washington, FM-20, Seattle, Washington 98195 Received 1990 May 31, revised 1990 August 17 ABSTRACT Narrow-band CCD H{alpha} imaging of the Local Group irregular galaxy IC 1613 has revealed a total of 77 H II regions, five of which are complexes of several smaller emission regions. Positions, H{alpha} luminosities, and sizes of these objects are tabulated. The H{alpha} luminosity function has the same shape as that for more luminous galaxies, following a power law with an exponent of -1.6. The faintest H II regions are at the low-luminosity end of the generally observed luminosity function for H II regions in galaxies, with fluxes of only ~10^35^erg/sec. The size distribution has an exponential shape, as for other galaxies, with a size scale of 56 pc. The morphologies of different H II regions are discussed and compared to those in other galaxies. Published radio continuum maps compare well with the H{alpha} emission distribution. The distribution of H I is also similar in the central areas to the H II with, however, a tendency for the H II regions to lie to one side of H I peaks. Key words: H II regions-irregular galaxy-Local Group
