Table containing the cooling tracks for an ultra-massive white dwarf of 1.159Msun with carbon-oxygen cores resulting from two single evolution scenarios. One scenario exploits wind rates and convective boundary uncertainties during the thermally-pulsing AGB phase, and involves the reduction of these rates below the values given by standard prescriptions (see, e.g., Decin et al. 2019). The other scenario requires the occurrence of rotation in degenerate CO cores, naturally expected as a consequence of core contraction at the end of core helium (He) exhaustion (Dominguez et al.1996). In addition, the table contains the cooling track for an ultra-massive white dwarf of 1.159Msun with oxygen-neon core resulting from off-center carbon-burning during the single evolution of the progenitor star, and a cooling track for an ultra-massive white dwarf of 1.159Msun with carbon-oxygen core resulting from white dwarf merger.
