MODELS OF THE DYNAMICS OF A SELF-GRAVITATING POLYTROPIC GAS
Zhuravlev V.M.
Using the method of hydrodynamic substitutions, a solution to the problem of the dynamics of a self-gravitating gas with a barotropic equation of state is constructed. Gas flow is described by Hubble’s law. The problem is solved within the framework of the classical theory of gravitation. A connection is established with the Emden-Lane theory of stellar polytropes.
Keywords: Dynamics of self-gravitating gas, Newton’s theory of gravity, Hubble’s flow, cosmology, evolution of stellar atmospheres.
