@article{Shu1977SelfsimilarCO, title={Self-similar collapse of isothermal spheres and star formation.}, author={Frank Hsia-San Shu}, journal={The Astrophysical Journal}, year={1977}, volume={214}, pages={488-497} }

We consider the problem of the gravitational collapse of isothermal spheres by applying the similarity method to the gas-dynamic flow. We argue that a previous solution obtained by Larson and Penston to describe the stages prior to core formation is physically artificial; however, we find that the flow following core formation does exhibit self-similar properties.The latter similarity solution shows that the inflow in the dense central regions proceeds virtually at free-fall before the material…
