Notes.

(a)

Degree of concentration of 22Ne in a central core with azeotropic abundance, X(22Ne) = 0.30.

(b)

Uniform composition through the whole WD, with X(22Ne) = Z and X(12C) = 1 − X(22Ne)−X(16O).

(c)

Half of all 22Ne concentrated in a central ball with the azeotropic composition; the other half uniformly distributed through the rest of the WD (case A in Fig. 1).

(d)

All 22Ne concentrated in a central ball with the azeotropic composition (case B in Fig. 1).

(e)

Enhanced 22Ne abundance in a narrow off-center shell (case C in Fig. 1).

(f)

Same as case B in Fig. 1 but with the same mass as the WD with uniform composition.
