Testing White Dwarf Age Estimates Using Wide Double White Dwarf Binaries from Gaia EDR3

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...
