Model atmosphere fitting of 25,642 cool white dwarfs in DESI DR1 finds no photometric-spectroscopic mass discrepancy for DAs, magnetic DAs at all temperatures, increasing H/He ratios in He-atmosphere stars below ~10,000 K, and a rising He-atmosphere fraction due to convective mixing.

In Tombaugh 2, 32% of blue straggler stars show ultraviolet excess from hot companions consistent with recent binary mass transfer, supporting this channel over mergers in a low-density cluster.
