v17 v18 41 41 === Summary === 42 42 43 The Shu solution begins from core formation (born out of a singular isothermal sphere) and initiates collapse into the medium through an 'expansion wave'. In contrast, the LP solution follows the collapse of a uniformly dense, static sphere prior to and up to core formation. This leads to a solution of homologous infall.Hunter, however, found that the LP solution can in fact be extended past core formation. The Shu solution evolves to a solution similar to homologous inflow like the LP solution.43 The Shu solution begins from core formation (born out of a singular isothermal sphere) and initiates collapse into the medium through an 'expansion wave'.

The ambient therefore had a large sound speed throughout the constant pressure medium, that remained nearly constant throughout. The results are robustly similar to the LP solution.
