Normalized Radius
Fig. 6.9 Pressure as a function of normalized radius is shown during the continued expansion of
the isothermal sphere at the times indicated. For the numerical procedure the following parameters
apply; Δλ ¼ 0.000457, λ s ¼ 0.0457, κ ¼ 1.2, Δτ ¼ 3 Â 10
À6 and γ ¼ 1.4
Fig. 6.10 Pressure as a function of normalized radius is shown during the late stages of the
expansion of the isothermal sphere at the times indicated. For the numerical procedure the following
parameters apply; Δλ ¼ 0.00457, λ s ¼ 0.0457, κ ¼ 1.2, Δτ ¼ 6 Â 10
À5 and γ ¼ 1.4
