Effects of high radial velocities on line transfer in extended atmospheres

Peraiah, A (Copernicus Foundation for Polish Academy, 1980)

The equation of radiative transfer in a comoving frame has been solved for rapidly expanding gaseous medium in spherically symmetric extended stellar atmospheres. A non-LTE two-level atom with Voigt profile function is ...
The interaction principle in radiative transfer

Peraiah, A (D. Reidel Publishing Co., 1984-10)

We describe the interaction principle which is of fundamental importance to the theory of radiative transfer in one-, two-, and three-dimensional geometry. We also describe the practical difficulties associated with this ...
Resonance line polarization in spherical atmospheres: Partial redistribution effects studied with the Domke-Hubeny redistribution matrix

Nagendra, K. N (The American Astronomical Society, 1994-09)

The problem of resonance line polarization including collisional redistribution is studied using simple theoretical models. The medium is assumed to be a static finite spherical shell atmosphere. The purpose of this paper ...
