A spectral diagnostic for density-bounded HII regions
The existence of density-bounded HII regions in spiral galaxies is supported by means of a spectral indicator based on the intensity of the [OI]λ6300 forbidden line. A grid of photoionization models providing spectral information on density-bounded nebulae is presented in order to test the validity of our indicator. The indicator is applicable to
