The extreme outer layers of supernovae, novae, AGN, QSOs, and many supergiant stars are known to be in rapid expansion or contraction. In this paper, aberration and advection effects in a spherical medium scattering radiation ...

The radiative transfer equation with Compton scattering is solved for spherically symmetric shells. The purpose of the study is to determine how gamma rays or X-rays change their energies and how they become reflected and ...
