The H II regions of Sextans A.

HODGE P., KENNICUTT R.C. and STROBEL N.

Abstract (from CDS):

Calibrated H-alpha and continuum CCD frames are used to measure the emission-line luminosities, sizes and morphological characteristics of 25 H II regions in the dwarf irregular galaxy Sextans A, a probable member of the Local Group. The luminosity function fits a power law with slope–1.70 and the size distribution is roughly exponential with a scale length of 62 pc. We identify 56 candidate exciting stars, from which we find that the estimated ultraviolet flux in the H II regions is approximately proportional to the H-alpha flux. Comparison with the H I distribution shows good positional agreement, except with an approximate 300 pc offset of H-alpha peak from H I peak.
