Internal chemical profiles of ¹⁶O (solid lines) and ²⁰Ne (dashed lines) in terms of the fractional mass for the 1.29 M_⊙ ONe-core WD sequence corresponding to various percentages of crystallization. The thick black lines correspond to the profiles before crystallization, and the thin lines of different colors correspond to the chemical profiles resulting from chemical rehomogenization for different effective temperatures at increasing percentages of crystallized mass fraction, as indicated for some selected cases. The thick red curves correspond to a model with T_eff = 4046 K and a percentage of 99.99% of crystallized mass.
