Abstract: Using a framework of the radiation approximation followed
by a two-term perturbation expansion for cosmic ray transport in the spherical
polar coordinates (r, θ, φ) researchers identify the effect of cosmic ray
radiation on shock dominated transport. When the buoyancy parameter Fr
is negligible, researchers find that the cosmic ray density at shock boundary
(En) decreases with increasing temperature. It is also observed that
the variation of radiation parameter N in cosmic ray transport has no significant
effect in the temperature distribution. Thus, even when radiation is significant,
it does not really modify the temperature within the cosmic ray region. However,
for increases in the density at shock boundaries say (En), the temperature distribution
decreases.
