Modelos numéricos de nubes cósmicas en contracción gravitatoria

Abstract

Starting from uniform distributions of density and temperature, the hydro-dynamical equations are integrated for contracting spherical masses of pure atomic hydrogen without radiation. We found a monotonic increase of density and temperature in the time. The space distributions of density and temperature are uniform but the velocity field is linear with distance from the center. As the paper will be published elsewhere we give here only a synthesis.
