The influence of the total optical depth towards distortions of the outer layers of a star

Theoretically the angular distributions of polarizations from the extended stellar atmosphere have been computed for the total optical depth up to 100. The atmosphere has been assumed plane-parallel.From the calculated results, it has been found that the polarization is dependent on the total optical depth and has its maximum value at a particular total optical depth 10. As regards polarizations due to asymmetries and distortions of the outer layers of a stellar body, we conclude that these asymmetries and distortions of the outer layers are dependent on the total optical depth and are maximum at a particular total optical depth.
