A Test of Spectroscopic Age Estimates of White Dwarfs using Wide WD+WD Binaries
Tyler M. Heintz, J. J. Hermes, P. -E. Tremblay +4
White dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic obser…
