Some observational manifestations of the periodic inhomogeneity of absorbing and scattering atmospheres

Abstract

We consider frequency and directional features of the reflectance and transmittance of an inhomogeneous scattering and absorbing atmosphere with the scattering albedo periodically varying with depth. The dependence of global optical properties of such media on optical thickness is found. Two different kind of problems are considered dependent on that by monochromatic or continuum, mono-directional or diffuse radiation illuminate the medium. The numerical results show how the observed intensities and line-profiles respond to the medium inhomogeneity with an uniform increase in optical thickness. Astrophysical aspects of these features are discussed.
