Log‐log plot of ﹩\tilde{\rho }\left[\theta _{\mathrm{ap}\,}( t_{c}) ,t\right]﹩ near ﹩t=t_{c}﹩ for the ﹩n=1﹩, ﹩p=0﹩ self‐similar solution. The density is plotted in arbitrary units and the time in units of ﹩1/ \Delta \Omega ﹩. The dashed line represents the asymptotic solution ﹩\tilde{\rho }( \theta _{\mathrm{ap}\,},t) \propto ( t_{c}-t) ^{4}﹩ derived in the text.
