Reflection nebula in the far-ultraviolet. 2. Silicate and graphite grains

Abstract

Simple models of the reflection nebula in the form of homogeneous plane-parallel slab containing single scattering silicate and graphite grains taken one species at a time have been considered in view of the far-ultraviolet surface brightness observations obtained from the ANS satellite. The colour difference between the star and the nebula as well the polarization of the nebular light in the far-ultraviolet have also been given
