From spectroscopic and photoelectric data BD +16° 516 (V 471 Tau) is inferred to consist of a white dwarf of mass 0.72M⊙ and radius 0.012R⊙, with a detached K2V companion of mass 0.70R⊙ and radius 0.78R⊙; the separation of the two components is 3.02R⊙. The evolutionary history of the system is discussed.
