Evolutionary tracks from PGPUC (first and second columns) and VR (third and fourth columns) with the nominal masses of V69’s components (from Table 1; red tracks correspond to the secondary, while black tracks correspond to the primary), compared with the observations (Table 1) of the binary. Solid, dotted, and dashed lines correspond to Y = 0.25, Y = 0.29, and Y = 0.33, respectively. All models were computed with [α/Fe] = 0.3. The VR tracks have [Fe/H] = −0.7, while the PGPUC tracks have Z = 0.0057, which at Y = 0.25 corresponds to [Fe/H] = −0.7. The VR tracks are interpolated following the procedure explained in Appendix A.
