(a) vs. obtained from the numerical integration of the 1-d moving boundary model with and . Continuous lines represent the best fit curves (equation (28)) with , , and . (b) Shrinkage factor obtained with the linear approximation (equation (13)) and with the nonlinear approximation (equations (28) and (29)). For both figures, (equation (16)).
