Abstract
An analytical representation of the density distribution of rapidly rotating superdense Newtonian polytropes is obtained in terms of polynomials in powers of flatness parameters e and the polytropic index approximating it with an error of 10−3. A scheme of the determination of critical points in the configuration density distribution is constructed. If n = 1.4, the values of the parameters characterizing an analytical representation of density near the critical points are obtained. The dynamics of critical points depending on the parameter e is studied. The formation of A 2- and A 3-type catastrophes is demonstrated. It is proven that a bubble domain in the shape of an elliptical torus is formed in the density distribution near the point e = 0.3503.
