Scientific paper

A fluid dynamics model is proposed to account for the evolution of various astrophysical hierarchies, including stellar, solar, planetary and satellite systems. The dynamics of the discontinuous evaporation and discontinuous absorption of drops of fluid solutions is examined, and a sequence of pulsations, implosions, radial jets, solvent emission leading to discrete episodes of mass loss, and concentric solute sedimentation common to all scales of evaporating drops is indicated. These sequential events are shown to have homomorphic analogs in astrophysical systems at different levels if the hydrogen-helium phase is represented as the solvent and sparse particulate dispersals of higher molecular weight are taken as the solute. It is argued that the analogies presented justify a unified model capable of explaining the course of stellar evolution based on the behavior of a fluid drop.
