New
ultra-massive ONe white dwarf evolutionary sequences (**article**)
that take into account the process of phase separation expected
during the crystallization stage based on phase diagram of dense
oxygen/neon mixtures. Realistic chemical profiles resulting from the
full computation of progenitor evolution during the semi-degenerate
carbon burning along the super-AGB phase are also considered in our
sequences. Outer boundary conditions for our evolving models are
provided by detailed non-gray white dwarf model atmospheres for
hydrogen and helium composition.
