RADIATIVE TRANSPORT OF HEAT IN LUNAR AND PLANETARY INTERIORS,
Abstract
The aim of the present investigation has been to formulate and solve the problem of the radiative transfer of energy in solid globes of planetary size - both in their interiors as well as surface layers - with the radiative loss into space taken into account. Following a general statement of this problem in the introductory section, the time-dependent partial differential equation of radiative transfer has been formulated in terms of spherical polar coordinates, and a method developed which permits the construction of a solution of this equation, to an arbitrary order of accuracy, both for the emissivity or temperature as the dependent variable. In the latter case, the well-known equation of heat conduction is shown to obtain as a limiting case if the mean free path of the energy-carrying photons tends to zero. (Author)
