Profiles of density, velocity (in units of 10⁷ cm s^-1), internal energy, and index of the sinc kernel at times t₁ = 870 s, t₂ = 1086 s, t₃ = 1311 s, corresponding to the collapse of a Sun-like polytrope. The lines in green, pink, and orange are for n adaptive and the blue, light blue, and black lines for n = 5 at the same elapsed times. The continuum lines in red have been obtained using a Lagrangian hydrocode with spherical symmetry.
