Testing White Dwarf Age Estimates Using Wide Double White Dwarf Binaries from Gaia EDR3
White dwarf (WD) stars evolve simply and predictably, making them reliable age indicators. However, self-consistent validation of the methods for determining WD total ages has yet to be widely performed. This work uses 1565 wide (>100 au) WD+WD binaries and 24 new triples containing at least two...
