Notes:   Confirmed binary, WD+dK2 (2MASS colors consistent with dK4-dM2), a = close (2007AJ....134...26H and references therein). Porb = 0.365 d (1996A&A...305L..45J). Originally discovered by EUVE as a composite spectrum object; optical identification from 1995MNRAS.274.1194M and 1997PASP..109..998S. The WD might be accreting from the wind of its ultra-fast rotating K2V companion (1996A&A...305L..45J, 1996A&A...315L..19J).
