N2 - Optical spectroscopy of the extreme ultraviolet source EUVE J1439+75.0 revealed a new unresolved double degenerate system. The system is composed of two hot white dwarfs (Teff ≥ 20 000 K), one magnetic (∼10 MG) and the other apparently non-magnetic. Surface gravity measurements imply masses of ∼1.0 and ∼0.9 M⊙ for the magnetic and non-magnetic white dwarfs, respectively. Proposed radial velocity and spectro-polarimetric studies may help uncover evidence of past interactions and clarify the evolutionary status of the pair.
