Effect of Radiative Heat Transfer on Cosmic-Ray Transport in a Rotating Cloudy Interstellar Medium

Pekene D.B.J, Ekpe O E

Radiative heat transfer on cosmic rays (cr) in a rotating cloudy interstellar medium is modelled by imposing  a time dependent perturbation on the cosmic transport in the interstellar medium containing randomly distributed giant diffused molecular clouds the temperature involved are assumed to be large so that radiative heat transfer is significant. This renders the problem very nonlinear even on the assumptions of a differential approximation for the radiative flux in a adiabatic concentration and zero activated energy. When the perturbation is small, the transient flow is tackled by the laplace transform technique, giving solution, for steady state spectrum of cosmic ray in the galaxy temperature up and down stream concentration, also velocity analytical and numerical solutions were obtained for temperature. Velocity of the down and upstream concentration in cases where radiative heat transfer through the rotating medium are taken into account. The incorporation of radiative heat transfer is of particular relevance to cosmic ray transport whose temperature is usually very high which radiate a lot of heat through the media which surround them.
