dc.description.abstract	The effects of aberration and advection terms in the fluid-frame steady-state radiative-transfer equation are evaluated by means of numerical computations for plane-parallel media moving at velocities 1000, 2000, 3000, 4000, and 5000 km/s. A monochromatic radiation field, no internal emission, and coherent isotropic scattering are assumed; the results are presented graphically and briefly characterized. The inclusion of aberration and advection is shown to produce substantial changes in the mean intensities and outward fluxes, even when time dependency is neglected. Application of the results to models of light propagation through the rapidly expanding outer layers of supergiants, novae, supernovae, QSOs, etc. is recommended.	en
