ON THE TIME-DEPENDENT PRINCIPLE OF INVARIANCE IN A SEMI-INFINITE MEDIUM

Journal Article · · J. Math. Anal. and Appls.
For a semi-infinite medium in which the particle mean free time is much greater than the mean survival time of a photon (e.g,, envelopes of novae, planetary nebulae, and cosmic clouds), a radiative transfer theory is derived that tekes into account the irreversible leakage of radiation from the system. The time-dependent diffusion problem posed by this theory is solved by means of a transient scattering function. The explicit form of the integral equation for this scattering function is obtained.
