White dwarf physical properties. (Top) Fit of the white dwarf spectral energy distribution probed using 9 photometric bands, W2 (red) was excluded from the fit. It converges to a DA white dwarf with Teff = 5968 ± 124K, Teff = 5986 ± 72 K, and surface gravity of ﹩\mathrm{log}g=8.03\pm 0.02﹩. The model and photometric fit are plotted in orange, and the photometric data used for fitting are represented by the black error bars. (Bottom) Best estimates of the final white dwarf mass, initial main-sequence mass, white dwarf cooling age, main-sequence lifetime, and total system age based on the wdwarfdate Python package (R. Kiman et al. 2022) using the above temperature and gravity as inputs.
