A COMPUTER MODEL FOR PLANETARY NEBULAE.

Abstract

A treatment of the planetary nebulae problem in which a computer model is constructed that will produce a consistent solution for such variables, within the nebular shell, as the radiation field, electron temperature, ionization densities, and expansion velocities of the elements. The nebula is characterized by such parameters as the average density of particle, average expansion velocity, size, relative abundances, and temperature of the central star. An equal measure of treatment is provided the three physical problem areas associated with planetary nebulae: radiative transfer, gas dynamics, and gas structure. The problem is treated in as much detail and accuracy as is consistent with both available computers and inherent observational inaccuracies. (Author)
