SPECTRAL TYPES OF IONIZING STARS AND THE INFRARED MORPHOLOGY OF HII REGIONS

Abstract

A previously developed catalog is presented, which includes 99 regions of ionized hydrogen (HII). Results of the flux measurements in the infrared (IR) and radio continua in the direction of the HII region are presented. Estimated fluxes of IR emission are compared to results from other catalogs. Spectral types of ionizing stars are determined for 42 regions with distance estimates available.
