Descripción
The effect of scattering by dust internal to H II regions on their
spectral characteristics has been studied on the basis of simple
analytical models, for assumed universal optical parameters of the dust.
A procedure to determine the external interstellar extinction and the
internal gas to dust abundance ratio of H II regions has been developed
and applied as a test to the Orion Nebula. Newly acquired observations
of the H II region NGC 896 have been analyzed to identify the effects of
internal dust on its spectrum and to establish its relationship to the
background radio source W3 (cont.). Finally, the effects that the
probable existence of scattering dust internal to HH-objects might have
on the color of their spectrum has been included.
