Abundance by mass of 1H, 4He, 12C, 14N, 16O, and 22Ne in terms of the outer mass coordinate for our 0.5281, 0.5759, 0.6573, and 0.8328 M⊙ WD models at the domain of the pulsating ZZ Ceti stars. Our new chemical profiles are compared with those we used in R12 of similar stellar masses (thick and thin lines, respectively).
