- W1985734780 abstract "A new method of successive approximations is developed to solve transfer problems in spherical coordinates. It is equivalent to methods involving the introduction of a closure relation for the μm-moment system. From a practical point of view, it is a two-direction method with variable quadrature weights which are easily computable for any depth variation of the opacity. These quadrature weights are taken as new variables; this allows us, even in the lowest orders, to dispose of closure relations that take into account the principal properties of the radiation field in spherical systems: quasi-isotropic radiation at great optical depths and unidirectional beam “peaking effect” at large values of the radial distance. In the first approximation, we find simple properties like those of the first order in the discretization method for plane-parallel systems. Therefore, it is formally possible to identify these two methods which have a similar practical application. We find for the mean intensity J(r), in the Milne problem, an analytical expression which corresponds to J = 3H(τ + cte) in the plane-parallel geometry. This work is a generalization of several important aspects of another study published in 1976 from which we have only kept the formalism. The new closure relation for the moment system is physically more complete and permits the development of new important results and allows the possibility of an easy solution in every order. From the first results obtained here, we show and analyze the differences between this study and the preceding one." @default.
