    4343The 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. 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.

    45 Authors ran simulations of a Bonner Ebert sphere with an outer density of 1/1000 the density at the outermost edge of the clump (my simulations used 1/100). 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.
